It's not easy to summarize our purpose because there are so many different aspects to it (e.g., our purpose as individuals, as a church, at home, in the world, etc.). But here is a general statement that covers all those aspects:

Our purpose is help people come to faith in Jesus, live out their faith, and grow in their faith according to the Bible.


AS CHRISTIANS

As Christians, our purpose is to honor Jesus as a way of life in all areas of life based on truth. 

Matthew 10:25a, "It is enough for the disciple to be like his teacher, and the servant like his master."

Ephesians 5:1–2, "Therefore be imitators of God, as beloved children. [2] And walk in love, as Christ loved us and gave himself up for us, a fragrant offering and sacrifice to God."

Colossians 3:17, "And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him."

2 Corinthians 5:15, "and he died for all, that those who live might no longer live for themselves but for him who for their sake died and was raised."

1 Peter 1:14–16, "As obedient children, do not be conformed to the passions of your former ignorance, [15] but as he who called you is holy, you also be holy in all your conduct, [16] since it is written, 'You shall be holy, for I am holy.'" 

Romans 14:7–8, "For none of us lives to himself, and none of us dies to himself. [8] For if we live, we live to the Lord, and if we die, we die to the Lord. So then, whether we live or whether we die, we are the Lord's."

2 Corinthians 5:9–10, "So whether we are at home or away, we make it our aim to please him. [10] For we must all appear before the judgment seat of Christ, so that each one may receive what is due for what he has done in the body, whether good or evil."

2 Corinthians 3:18, "And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit."

Romans 12:1–2, "I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. [2] Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect."

1 Corinthians 6:18–20, "Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body. [19] Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, [20] for you were bought with a price. So glorify God in your body."

Galatians 5:19–26, "Now the works of the flesh are evident: sexual immorality, impurity, sensuality, [20] idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, [21] envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God. [22] But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, [23] gentleness, self-control; against such things there is no law. [24] And those who belong to Christ Jesus have crucified the flesh with its passions and desires. [25] If we live by the Spirit, let us also keep in step with the Spirit. [26] Let us not become conceited, provoking one another, envying one another."

1 Peter 2:11, "Beloved, I urge you as sojourners and exiles to abstain from the passions of the flesh, which wage war against your soul."

1 Peter 2:9–10, "But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. [10] Once you were not a people, but now you are God's people; once you had not received mercy, but now you have received mercy."

AS A CHURCH

As a church, our purpose is to honor Jesus as LORD, make and baptize disciples of Jesus, and learn to obey Jesus in faith and practice according to truth.

Psalm 22:27–28, "All the ends of the earth shall remember and turn to the LORD, and all the families of the nations shall worship before you. [28] For kingship belongs to the LORD, and he rules over the nations."

Hebrews 10:23–25, "Let us hold fast the confession of our hope without wavering, for he who promised is faithful. [24] And let us consider how to stir up one another to love and good works, [25] not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near. (ESV)

1 Peter 2:9–10, "But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. [10] Once you were not a people, but now you are God's people; once you had not received mercy, but now you have received mercy."

Matthew 16:18–19, "And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it. [19] I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven." 

Hebrews 12:28–29, "Therefore let us be grateful for receiving a kingdom that cannot be shaken, and thus let us offer to God acceptable worship, with reverence and awe, [29] for our God is a consuming fire."

Matthew 28:18–20, "And Jesus came and said to them, 'All authority in heaven and on earth has been given to me. [19] Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, [20] teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.'"

John 20:20–23, "When he had said this, he showed them his hands and his side. Then the disciples were glad when they saw the Lord. [21] Jesus said to them again, 'Peace be with you. As the Father has sent me, even so I am sending you.' [22] And when he had said this, he breathed on them and said to them, 'Receive the Holy Spirit. [23] If you forgive the sins of any, they are forgiven them; if you withhold forgiveness from any, it is withheld.'"

1 Corinthians 11:23–26, "For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, [24] and when he had given thanks, he broke it, and said, 'This is my body, which is for you. Do this in remembrance of me.' [25] In the same way also he took the cup, after supper, saying, 'This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.' [26] For as often as you eat this bread and drink the cup, you proclaim the Lord's death until he comes."
