'Worthy' in the Bible

I indeed am baptizing you in water on a profession of repentance; but He who is coming after me is mightier than I: His sandals I am not worthy to carry for a moment; He will baptize you in the Holy Spirit and in fire.

Any one who loves father or mother more than me is not worthy of me, and any one who loves son or daughter more than me is not worthy of me;

and any one who does not take up his cross and follow where I lead is not worthy of me.
