And if children, then heirs; heirs of God, and joint-heirs with Christ… – Romans 8:17

Oh! heir of heaven, if thou art God’s child, wilt thou not love thy Father? What son is there that loveth not his father?  And we, the chosen favourites of heaven, adopted and regenerated, shall not we love Him? Shall we not say, “Whom have I in heaven but Thee, and there is none upon earth that I desire in comparison with Thee? My Father, I will give Thee my heart; Thou shalt be the guide of my youth; Thou dost love me, and the little heart that I have shall be all Thine own for ever.”

Furthermore, if we say “Our Father which art in heaven,” we must recollect that our being sons involves the duty of obedience to God. When I say “My Father,” it is not for me to rise up and go in rebellion against His wishes; if He be Father, let me note His commands, and let me reverentially obey; if He hath said “Do this,” let me do it, not because I dread Him, but because I love Him; and if He forbids me to do anything, let me avoid it. There are some persons in the world who have not the spirit of adoption, and they can never be brought to do a thing unless they see some advantage to themselves in it; but with the child of God, there is no motive at all; he can boldly say, “I have never done a right thing since I have followed Christ because I hoped to get to heaven by it, nor have I ever avoided a wrong thing because I was afraid of being damned.” For the child of God knows his good works do not make him acceptable to God, for he was acceptable to God by Jesus Christ long before he had any good works; and the fear of hell does not affect him, for he knows that he is delivered from that, and shall never come into condemnation, having passed from death unto life.

“Now for the love I bear His name,
What was my gain I count my loss;
I pour contempt on all my shame,
And nail my glory to His cross”-

to His cross who loved, and lived, and died for me who loved Him not, but who desires now to love Him with all my heart, and soul, and strength. ~ C.H. Spurgeon
