If there is anything that can be sure about God, it is that He longs to have every human come to Him. He created man in the first place to have fellowship with Him, but God cannot commune with sin, so when man disobeyed, sinned, and brought sin into the perfect world God had created, there had to be a way to breach or bridge the gap that came between God and man. In the Old Testament, it was through offerings and sacrifices of lambs and bulls, but humans were unable to keep the Law, they just kept adding to the Law, making it all the more impossible to live.
All through the Old Testament, God reveals His plan to send the Messiah, the perfect sacrifice for mankind. In each book, Genesis through Malachi, there is a consistent thread, a type and shadow, that predicts God will send Jesus to redeem and save man.
God always has and always will be the Father standing at the end of the road watching to see if today his child will come home. He has made every provision possible that we may know Him and be in right relationship with Him, even to the point of giving His only Son as the sacrifice, the Holy Lamb of God whose blood could cover our sin.
As the scripture in the book of Joel says, "it isn't too late". This is good news! No matter how far down we may have gone, God says it's NOT too late to come back to Him with all our heart.
Luke 15:11-24 (King James Bible) The Parable of the Lost Son
vs. 20 And he arose, and came to his father. But when he was yet a great way off, his father saw him, and had compassion, and ran, and fell on his neck, and kissed him. 21 And the son said unto him, Father, I have sinned against heaven, and in thy sight, and am no more worthy to be called thy son. 22 But the father said to his servants, Bring forth the best robe, and put it on him; and put a ring on his hand, and shoes on his feet. 23 and bring hither the fatted calf, and kill it; and let us eat, and be merry. 24 for this my son was dead, and is alive again; he was lost, and is found. And they began to be merry.
It's not too late!!
