We are saved by faith in the Lord Jesus Christ. God's grace was freely given to us through faith in Christ. We become heirs of God, and joint-heirs with Christ (Romans 8:16-18). Upon believing in Jesus Christ our Lord, we are saved (Acts 16:31).
We are saved in Christ by grace alone. Salvation can never be bought, earned, nor achieved through personal effort. Grace is received freely as the gift of God. Saving grace in Christ is received with new life, abundant life, and life eternal (Romans 6:23). So, we can testify, But by the grace of God I am what I am (1 Corinthians 15:10).
We are saved as believers in Christ through the Holy Spirit (John 3:6-7). No one else in all the world can change you but the Spirit of Christ (Romans 8:9). The Holy Spirit operated directly on our hearts, to change us from the inside out. The Holy Spirit changes our mind to understand the things of God (Romans 12:2). The Holy Spirit changes our will to repent (Philippians 2:13). The Holy Spirit changes our emotions to have a tender heart toward God (Ephesians 4:32).
We are saved unto a future to be glorified into the image and likeness of Jesus Christ (Romans 8:28-30). Our eternal future is sure in Christ. The God of all grace changes us from glory into glory through Jesus Christ our Lord. We shall receive a glorified body like that of our Lord Jesus Christ (1 John 3:2).
