Matthew 10:40 He that receiveth you receiveth me, and he that receiveth me receiveth him that sent me.
The way we treat God’s men shows our reaction to Him. If the Jews would receive the apostles when then went to their cities then they would be receiving Jesus and also the Father that sent Him.
People who hate God will hate God’s people. We shouldn’t be surprised to find that people react ugly towards us when we love Jesus and express that. They are not rejecting us but Him.
So go out and be confident as you present Jesus. Realize that it is not personal reject but actually a rejection of Jesus and God Himself.
This can give us confidence in preaching as we know we are not out pushing ourselves or our own agenda.
