“Lose the gift of eternal life”
Do you see the oxymoron in this?
Any gift your parents gave you, you accepted (in your heart, maybe, rejected as you didn't like it) and then you misplaced it/lost it and, maybe, found it again or you threw it away coz you didn't want it .. Salvation is a gift for ALL bought and paid for by Jesus Christ giving His life on the cross. We can accept it or reject it. If we accept it, we can, later, lose it by unrepentant sinning or we can choose to throw it away by choosing to sin and not repent. This is not rocket science and no oxymoron.
