“I baptize with water; but there is one among you whom you do not recognize, the one who is coming after me, whose sandal strap I am not worthy to untie.” This happened in Bethany across the Jordan, where John was baptizing. John 1:26–28
“If I do not perform my Father’s works, do not believe me; but if I perform them, even if you do not believe me, believe the works, so that you may realize and understand that the Father is in me and I am in the Father.” John 10:37–39
