Our Father God in heaven loves us so much. That is why He tells us that, “. . . I have loved you with an everlasting love; Therefore with lovingkindness I have drawn you” (Jeremiah 31:3). That is why He gave up His only begotten Son Jesus to die in our place. We were separated from God by sin. But by the death of Jesus, that gap of separation was bridged, so that we can be one with our Father for all eternity. There has never been, and will never be a greater love story than that. Hence 1 John 3:1: Behold what manner of love that Father has bestowed on us, that we should be called children of God!
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.
