Thank God for earthly fathers; but none is like He who art in heaven. Fathers beget, provide, protect, encourage, counsel etc. Yet true of the Father above, He does a better job than the ones on earth. That is why we really need to know God as Father.
It is important to reiterate that for us Christians, God is more than God – He is our Father. This is the highest revelation that there is of God. It is for this reason that we must pray continuously for that revelation to become real to us in ever increasing measure.
