2 Thessalonians 2:13 (KJV) But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth:
Do you understand this? God has chosen you! Because you repented of your sins, and called out to Him to save you, He has chosen you. We are saved by trusting in Jesus and His sacrifice on the cross. We are sanctified by continuing to trust in what He did. It does no good to trust in man, or even the church. It takes trusting in Jesus and His work on the cross.
(Read 1 Peter 1:2)
