I couldn't sleep last night, so turned on "Turning Point" with Dr. David Jeremiah. Perfect. It had a bit of perspective about rejection. These are points that I got from his message.
He taught that Jesus was rejected His whole life. The one who saved you from your sin has felt the sting of rejection. What did He say about it? Shake the dust off your feet and go on. Get on with life. God's already prepared other people who will receive you.
You cannot get someone to be who they are not. You cannot change someone. We are not responsible for what other people do to us. Rejecting a Child of God is a serious offense. God says if you are a rejector it is more profitable for you than it was for Sodom and Gomorrah. You can shake off being rejected, but you cannot shake off being the rejector, because it will come back. God is the great avenger, and He will make all things right. Leave it up to Him.
While we can be rejected here by people who know us, and have grown up with us and supposedly love us, we will never be rejected by the Lord. We are accepted in the Beloved. God is continually accepting people into His family. We go though life always trying to find our way, bumping our noses into the wall, till one day somebody crosses our path and says "There is a God in Heaven who has put his hand on you, and He has said 'I want this one for me.'" Then it is that we intimately know what it means to be accepted. That doesn't mean that all rejection in our human life goes away, but it means the ultimate form of acception has already taken place. We have been accepted by God. He wants you for himself.
