Think of a gift card. Starts with an urge to give the opportunity to use freely. Then a purchase of a certain amount is made. Then a card holds that amount. Then it is gifted. Then the giftee is accounted to redeem the amount to receive something freely.
So. With our Creator. Who wanted to gift us to be with him. He purchased a price. The price equal to a perfect eternal life. Enough to pay for the sins of all humanity. This price was bought by the amount of the pure blood of Jesus the son of God. And redemption is found in the resurrection of Jesus Christ so that we may choose to buy our salvation upon the sacrifice spent on the cross to be free from sin.
Eternal life is the gift. Jesus is the gift card. Heaven is the place we are receiving when we redeem this gift. Don't let your gift card expire. Go. And make the transaction.
John 14:6 New International Version Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me.
