Martin it is not by works that we are saved but by grace that none should boast.Works do not get us us closer to God but good works come from a
heart that loves God and desires to please him.John 3:16 is clear if we believe in Jesus Christ we shall have eternal life it is based not on what we do or have done but by the grace of God that has been
poured out
upon us because of Jesus Christ.God always gives us assurances or promises the condition to receive eternal life is to believe in Jesus Christ as the one who has saved from our sin.Personally i believe that the continued walk will determine our reward from the Lord again its not based on our effort but a trust or faith in God.This does not effect the gift of eternal life through Jesus Christ.
