Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law.Romans 3:31
When the believer is adopted into the Lord's family, his relationship to old Adam and the law ceases at once; but then he is under a new rule and a new covenant. Believer, you are God's child; it is your first duty to obey your heavenly Father.
A servile spirit you have nothing to do with: You are not a slave but a child. And now, inasmuch as you are a beloved child, you are bound to obey your Father's faintest wish, the least intimation of His will. Does He bid you fulfill a sacred ordinance? It is at your peril that you neglect it, for you will be disobeying your Father.
Does He command you to seek the image of Jesus? Is it not your joy to do so? Does Jesus tell you, "You therefore must be perfect, as your heavenly Father is perfect"? 1 Then not because the law commands, but because your Savior enjoins, you will labor to be perfect in holiness. Does He bid his saints to love one another? Do it, not because the law says, "Love your neighbor," but because Jesus says, "If you love me, you will keep my commandments." 2
And this is the commandment that He has given unto you, "that you love one another." Are you told to distribute to the poor? Do it, not because charity is a burden that you dare not shirk, but because Jesus teaches, "Give to him that asks of you." Does the Word say, "Love God with all your heart"? Look at the commandment and reply, "Ah, commandment, Christ has fulfilled you already. I have no need, therefore, to fulfill you for my salvation, but I rejoice to yield obedience to you because God is my Father now, and He has a claim upon me, which I would not dispute."
May the Holy Ghost make your heart obedient to the constraining power of Christ's love, that your prayer may be, "I will run in the way of your commandments when you enlarge my heart!" 3 Grace is the mother and nurse of holiness, and not the apologist of sin.
