The truth is God and God is love. If one does not have love, then one does not have heaven within and he or she is already living in hell on earth. Love, being God, is our salvation from a hell within us of our own making. My son, do not make light of the Lord's discipline, and do not lose heart when he rebukes you, because the Lord disciplines those he loves , and he punishes everyone he accepts as a son. Since God loves the whole world, it would be safe to say God disciplines everyone.
Love is certainly a task-master.
But perfect love drives out fear , because fear has to do with punishment. The one who fears is not made perfect in love. The one who fears God is only beginning to be wise. Advanced wisdom comes when fear is replaced with love. Preachers who like to preach fear instead of love to gain converts are not being very wise.
