'For this my son was dead and is alive again; he was lost and is found.' And they began to be merry.
In Luke 15, starting in verse 11, Jesus tells a parable which illustrates how God longs for us to return to Him if we have wandered away in sin. The parable tells of a son who took his inheritance and went away from his father into a far country and wasted his inheritance in riotous living. He became destitute and hired out to feed pigs. He became so hungry he even wanted to eat what the pigs ate. He decided to go back to his father and hire out as one of his hired servants. Verse 20 says, "And he rose and came to his father. But when he was still a great way off, his father saw him and had compassion, and ran and fell on his neck and kissed him."
In this parable the father represents God. Christ gave us this parable to show how anxious God is to have us come back if we have wandered away from Him in sin. God will run to us with open arms if we will only come back to Him.
