What we Believe

At Thu Thiem International Service…

Our core beliefs are rooted in Scripture, rather than speculation or tradition. Though we seek to be relevant to the times, we choose to anchor ourselves to the Rock of timeless truth. What follows are some of those timeless truths, with Scripture references included.


We believe the Bible (every verse in all 66 books) originated with and was breathed out by God. It speaks with the authority of God while at the same time reflecting the backgrounds, styles, and vocabularies of the various human authors. In its original manuscripts, it is infallible and inerrant. It is the full and final authority on all matters of faith and patience. No other writing is similarly inspired by God, nor has the Bible’s life-transforming power.

Therefore, it is to be thoughtfully and diligently, joyfully and prayerfully read and taught, memorised and meditated upon, understood and applied, believed and obeyed, trusted and applied.

2 Tim. 3:15-17, 2 Pet. 1:20-21, Prov. 30:5, Deut. 4:2, Ps. 19:7-9, Isa. 55:9-11, Neh. 8:1-2, Josh. 1:8, Rom. 10:17, James 1:21-25.


We believe God is uncreated, eternal, self-sustaining, unchanging, all-knowing, all-powerful, omni-present, and entirely wise, good, loving, gracious, compassionate, righteous, and holy. This one God eternally exists as a loving community of three equal persons – God the Father, God the Son, and God the Holy Spirit. They are equal in nature, but distinct in the role and relationship.

God created the universe, the world and everything in it. Through His sovereign authority and unrivalled power, God continues to sustain and govern His creation. He operates within and over every detail of history, past, present and future, as He fulfills His redemptive purposes.

Acts 17:24-25, Mal. 3:6, Ps. 90:2, Jer. 23:23-24, Isa. 46:9-10, Dan. 4:34-35, 1 John 3:20, Dan. 2:20, 1 John 4:8-10, Rev. 4:8, Deut. 6:4, 2 Cor.


We believe God created humankind, male and female in His own image and likeness with dignity and worth. He created us to worship, enjoy and love Him forever, and to be responsible stewards of His creation. Adam and Eve, sinfully defied God, corrupting the entire human race, alienating us from God, and bringing us under His righteous judgement.

Neither good deeds nor religious observance are able to restore this broken relationship with God. God lovingly took it upon Himself to restore us back to Himself. Through Abraham, He brought about the nation of Israel, a people to whom He progressively revealed Himself through saving deeds, covenants, prophets, signs and Scripture. God promised them the coming of a divine Savior for all people, a promise that was fulfilled in Jesus Christ over 2000 years ago.

Gen. 1:26-27, Ps. 95:6, Gen 2:15, Gen. 3:1-12, Ps. 51:4, Matt. 15:19, Rom. 3:22-23, 5:12, Eph. 2:1-3, Gen. 12:1-2, Heb. 1:1-2, Luke 24:25-27.


We believe that Jesus Christ is the eternal Son of God. He became fully human, while continuing to be fully God. He was conceived by the Holy Spirit, and was born of a virgin girl named Mary. He lived a sinless life that was marked by casting out demons, miracles and preaching the Kingdom of God. He related to the Father with perfect intimacy. He came to be the substitutionary sacrifice for humanity. His sacrifice provided the free gift of eternal life which includes forgiveness of sins, new life and adoption into God’s family.

He rose from the dead and ascended into heaven where He now sits at the right hand of the Father as the only mediator between a Holy God and sinful people. This gift of salvation is available to all who repent and trust in Christ alone as their saving Lord. He will personally and visibly return to earth in magnificent glory to judge the world and reign forever. All people and forces that oppose Him will be vanquished, including death itself.

John 1:1-2, John 1:14, Luke 1:35, John 5:19, 1 Pet. 2:24, 1 Pet. 1:3-5, Heb. 7:25, Heb. 9:24, Rom. 8:34, 1 John 2:1-2, Eph. 2:8-10, Eph. 1:5-7, 1 Tim. 2:5, Acts 16:31, Acts 1:9-11.


We believe the Holy Spirit is the primary person of the Trinity at work in applying the finished work of Christ, in the lives of God’s people. The Holy Spirit illumines the Bible, empowers Gospel preaching, brings regeneration and sanctifies the believer into the image of Christ. Scripture calls believers to glorify Christ. This calling is only possible through continual reliance on the Spirit’s presence, power, and leadership. The Holy Spirit reveals the Father and the Son to us, pouring out their love into our hearts, and conforming our characters to reflect theirs. This transformational process requires our participation, including whole-hearted trust and obedience, and the disciplined pursuit of God and His will. The Holy Spirit assures believers of their position as God’s child. The Holy Spirit draws unbelievers to trust in Christ. We believe all Christ followers are to live lives that are sensitive and responsive to the prompting, leading and specific guidance that He provides. Both the fruit of the Spirit and the gifts of the Spirit are essential to the life and ministry of the Church.

1 Cor. 6:19, John 16:13-14, Eph. 5:18, Acts 2:1-4, Rom. 5:8, 2 Cor. 3:18, Gal. 5:22-23, Rom. 8:16, Eph. 1:13, 2 Tim. 2:7, 1 Cor. 12:8-11, John 16:7, Eph. 4:3-4, Acts 1:8, Acts 2:39, 1 Cor. 12 and 1 Cor. 14:1-19.


We believe in salvation by grace alone through faith in Jesus Christ. This salvation is based upon the sovereign grace of God. It was purchased by Christ on the cross and is received through faith independent of any human merit, works or ritual. We believe salvation results in righteous living, good works, and proper social concern. We believe that all true believers, having been justified, shall be kept eternally secure (saved) forever. It is the unmerited grace and keeping and sustaining power of God that gives us this security.

John 3:16; Rom. 10:9-10; Eph. 2:8-9; Heb. 7:25; II Tim. 1:12; Heb. 10:10, 14; 1 Pet. 1:3-5; Rom. 8:1, 38, 39; John 10:27-30; Phi. 1:6.


We believe the Church is the community of God’s redeemed people. The Church is composed of all who have truly trusted Christ alone for their salvation. The Church is created by the Holy Spirit to exalt Jesus Christ as Lord of all. Christ is the Head, Lord, Savior and King of the Church. This one universal church finds expression in varied local churches. In each local church, believers are to be a spiritual family that regularly gathers for worship, prayer, the teaching of the Word, baptism and communion. Each church is to be led, equipped and cared for by elders and deacons, and each believer is to do all they can to strengthen the church through loving one another, protecting the unity of the church, and generously serving and giving. The priority of every church is to impact the world, and penetrate culture with the Good News of Jesus Christ in order to make disciples. The Church finds its joy in becoming the spotless bride of Christ, anticipating His personal, bodily and visible return.

1 Cor. 1:2, Heb. 10:25, Gal 6:10, Acts 2:41-47, 1 Tim. 5:17, Heb. 13:17, Eph. 4:11-12, Eph. 4:2-3, 1 John 3:16-18, 2 Cor. 9:7, 13, Rom. 12:4-8, Matt 4:19, Matt 28:18-20, Eph. 1:22-23, Matt 16:18.


We believe God is grieved and angered by sin, unbelief and rebellion. He promises to judge everything and everyone that contradicts his character and defies his will. Everyone lives once, and then faces God on Judgment Day, an event that will follow the return of Christ. Depending on whether we spurn or embrace Christ and his grace in this life, we will either suffer eternal condemnation without him, or be received into eternal communion with him. Depending on their faithfulness to Christ, believers will receive heavenly rewards. Believers should live in eager expectation and preparedness, which involves holy living and an eternal perspective.

Rom. 2:5, 3:19, Acts 17:30-31, Heb. 9:27, 2 Thes. 1:8-9, Rev. 14:9-11, Luke 23:39-43, Phil. 1:21-23, 1 Cor. 3:12-15, Col. 3:23-24.


We believe that at Christ’s resurrection He inaugurated His Kingdom on this earth. At His second coming, His kingdom will be fully realized and experienced: a redeemed humanity will enjoy immortal resurrection bodies as they celebrate God’s presence and grace forever in the new heaven and new earth, a world purged of all suffering, injustice, sin and death. The church is to live in joyful anticipation of this certain future. We do this through proclaiming the gospel, living counter – culturally, building authentic community, serving the poor and marginalized, confronting injustice, and protecting creation, all the time praying, “Your Kingdom come”.

Mark 1:14-15, 1 Cor. 15:51-54, Rev. 21:1-3, 22:1-5, Isa. 65:17-25, Matt 6:19-21, Heb. 6:5, Luke 24:46-49, Matt 5:13-16, John 13:34-35, Luke 10:27-37, Job 29:12-17, Matt 6:9-10.
