Humility comes from knowing that outside of Christ and what he works in you by the Holy Spirit, you are nothing. It comes from knowing that there is nothing in you deserving of God's favor, but that he nevertheless showers you with his favor due to the merits of Christ counted as yours through faith. Humility does not in any way come from seeing yourself as great, but from seeing Christ as great.

Amen. "I am the vine, you are the branches; apart from me, you can do nothing."
