Since God is above all things and He loves his creation, why should we worry about rejection or what happens? Everyone struggles and if you are one of those who just insist on not believing or trying to, this may not be for you. I hope you'll consider this and find it helpful.
He, (God), in His word, said All things work together to those who Love God, then I, you, we, don't have to carry the burden. He did and already proved so by dying a cruel death and get this, willingly! Something you or I don't have the strength or way to do.
When you realize this, then true freedom occurs and you'll witness incredible things in life and an ability to get through the hard stuff, even rejection from others.
The hardships of this life can never compare to what Jesus Christ gives to those who seek Him first and find Him. What others say in rejecting you comes to fact they are hurting but pray they find what you now have and for goodness sakes don't gloat over it because that's not good. Most important if you take away nothing else remember this, when we feel rejected by the world, try to imagine how many times we have rejected God and His Son and sometimes still do. Thank Him because He never has rejected us.
