“At that time Jesus came to Jericho and intended to pass through the town. Now a man there named Zacchaeus, who was a chief tax collector and also a wealthy man, was seeking to see who Jesus was; but he could not see him because of the crowd, for he was short in stature. So he ran ahead and climbed a sycamore tree in order to see Jesus, who was about to pass that way. When he reached the place, Jesus looked up and said, "Zacchaeus, come down quickly, for today I must stay at your house." And he came down quickly and received him with joy.
When they saw this, they began to grumble, saying, "He has gone to stay at the house of a sinner." But Zacchaeus stood there and said to the Lord, "Behold, half of my possessions, Lord, I shall give to the poor, and if I have extorted anything from anyone I shall repay it four times over." And Jesus said to him, "Today salvation has come to this house because this man too is a descendant of Abraham. For the Son of Man has come to seek and to save what was lost." -Luke 19:1-10
Christ calls out to all of us, “I must stay in your house.” Zacchaeus, like us, was not worthy of the Lord’s presence, but that was precisely why Jesus said He must stay. Unless we allow our Lord to enter into us, we have no hope of even realizing we are lost. But once Christ enters our soul, He shows us how cluttered it has become, and we desire to clear it out to make room for Him. It is never we who affect a change toward God. It is Christ who seeks out to save those who were lost. Once He enters, we will never be the same.
