Yet even this simple, lovely prayer resulted in no-end of criticism, such as: " God loves everybody!"
Does God love everybody? Can that generality be applied to every single individual? God hated Esau and refused to forgive him though he sought it with tears.
But the big issue here is not whether God loves all of us, but whether we experience that love. If love is only a feeling then we can never know God's love. But with God's love - love is an action verb. He commands us to love our neighbours by feeding the hungry, giving drink to the thirsty, sheltering the homeless, visiting the shut-ins, and clothing the naked.
When we 'experience' the joy of being loved by God, it is like being looked after by a loving neighbour. He takes care of our needs. He blesses us and you can feel His blessings and, at times, His very presence.
When you 'know' the Son of God for Who He really is, then you can 'experience' the love of God. Until then it is just a concept.
