What common goal do all religion share?

All religions teach us to believe in God, all religions teach us to love one another, to be kind and compassionate, all religions ask us to live a moral life. There may be different interpretations, and religions and followers of religions may do different things but the commonality between all religions is for us to love God, to seek God, and achieve God. Unfortunately, religions are only a kindergarten, they teach us the ABC of God, then we go round and round in a merry-go-round and we die without going beyond the kindergarten of religion. We don't need to change our religion, but we need to go beyond religion to the university of spirituality which will help us to realize God in the temple of our heart.
