“Question: But will God be a Father to me, who have profaned His name, and been a great sinner?
Answer: If thou wilt now at last seek to God by prayer, and break off thy sins, God hath the compassion of a Father for thee, and will in no wise cast thee out.
When the prodigal did arise and go to his father, ‘his father had compassion, and ran and fell on his neck, and kissed him,’ Luke 15:20.
Though thou hast been a prodigal, and almost spent all upon thy lusts, yet, if thou wilt give a bill of divorce to thy sins, and flee to God by repentance, know that He hath the compassion of a father.
He will embrace thee in the arms of His mercy, and seal thy pardon with a kiss. What though thy sins have been heinous?
The wound is not so broad as the plaster of Christ’s blood. The sea covers great rocks. The sea of God’s compassion can drown thy great sins.
Therefore be not discouraged,—go to God,—resolve to cast thyself upon His fatherly compassion.
What comfort is there to such as can upon good grounds call God, Father. There’s more sweetness in this word Father, than if we had ten thousand worlds.”
