When God saves you, it's by faith in Christ (Eph. 2:8-10). God's grace is freely given to you through faith in Christ. You become an heir of God, and a joint-heir with Christ (Romans 8:16-18). Upon believing in Jesus Christ our Lord, you are saved (Acts 16:31).
When God saves you, it's 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, you can testify, "But by the grace of God I am what I am" (1 Corinthians 15:10).
When God saves you, it's through the Holy Spirit (John 3:6-7). Nothing else in all the world can change you but the Spirit of Christ (Romans 8:9). The Holy Spirit operates directly on your heart, to change you from the inside out. The Holy Spirit changes your mind to understand the things of God (Romans 12:2). The Holy Spirit changes your will to repent (Philippians 2:13). The Holy Spirit changes your emotions to have a tender heart toward God (Ephesians 4:32).
When God saves you, it's unto a future to be glorified into the image and likeness of Jesus Christ (Romans 8:28-30). Your eternal future is sure in Christ. The God of all grace changes you from glory into glory through Jesus Christ our Lord. You shall receive a glorified body like that of our Lord Jesus Christ (1 John 3:2).
