Well; we DO know from Scripture that we CAN lose it by UNBELIEF.
Hebrews 3:12
See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God.
He who believes and is baptized will be saved; but he who does not believe will be condemned.
Mark 16:16
Matthew 24:10-13
At that time many will turn away from the faith and will betray and hate each other, and many false prophets will appear and deceive many people.
Because of the increase of wickedness, the love of most will grow cold, but the one who stands firm to the end will be saved.
1. Turning away is not the same as losing eternal life
2. “Does not believe” is contrasted with those who do believe and are saved.
3. Israel
“Thanks be to God for His indescribable Gift!”
