Titus 3:5 & 6 says “He saved us, not on the basis of deeds which we have done in righteousness, but according to His mercy……”
So, we are saved by faith and faith alone in Jesus Christ. He is the One whom God sent to deliver us from the penalty of sin by His death on the cross.
Many religions teach that you can be your own savior as you produce your own righteousness. This self righteousness is based upon your good deeds, works, and or following the rituals of that church. God says that Salvation is a free gift (Ephesians 2:8), so we know that we cannot work for or earn salvation.
Those who trust Jesus Christ as their Savior are at that point born of the Spirit and are assured of an eternity in Heaven. (Romans 5:6-9; Romans 4:5; Ephesians 2:8-9; John 3:5-18)
