Return, ye backsliding children, and I will heal your backslidings. 

Behold, we come unto Thee; for Thou art the LORD our God. – Jeremiah 3:22

“Return, ye backsliding children, and I will heal your backslidings.” Can you hear these words without emotion? Backslider! I pray thee take the wings of God’s love to fly back to Him with. But I hear you enquiring, Will He still receive me? Shall I be once more-

“To the Father’s bosom pressed,
Once again a child confessed.”

It shall be so. Does He not declare that He is God and changes not, and therefore you are not consumed? Rekindled are the flames of love in the backslider’s bosom when he feels all this to be true; he cries, “Behold, we come to Thee for Thou art the Lord our God.” I pray you, then, any of you who are conscious of gross derelictions of duty, and wanderings of heart, do not ask Moses to lead you back to Christ, he knows the way to Sinai’s flames, but not to Calvary’s pardoning blood. Go to Christ Himself at once. If you go to the law and begin to judge yourself, if you get the notion that you are to undergo a sort of spiritual quarantine, that you must pass through a mental purgatory before you may renew your faith in the Saviour, you are mistaken. Come just as you are, bad as you are, hardened, cold, dead as you feel yourselves to be, come even so, and believe in the boundless love of God in Christ Jesus. Then shall come the deep repentance; then shall come the brokenness of heart; then shall come the holy jealousy, the sacred hatred of sin, and the refining of the soul from all her dross; then, indeed, all good things shall come to restore your soul, and lead you in the paths of righteousness. Do not look for these first; that would be looking for the effects before the cause. The great cause of love in the restored backslider must still be the love of God to him, to whom he clings with a faith that dares not let go its hold. – C.H. Spurgeon
