Called, Chosen, Invited, and Welcomed

These are all New Testament words that are used to describe the overtures that God makes to man. I am not a scholar of the original languages, and make no claim to be, but it seems that there are fundamental differences in these terms that may be significant. "Many are called, but few are chosen" is one of the most intiguing passages in the Scriptures, and I think it is significant as an indicator of God's and our separate and distinct roles in salvation. Then we run across Luke 19:5, where Jesus interacts with Zaccheus. In this case, Jesus clearly announces his intention to relate to Zaccheus, who responds by "welcoming" him to his home. Was he called, chosen, or invited . . . what was Jesus' role in this interaction, and what was Zaccheus'? Then we get into predestination and free will, and my mind explodes . . .
