Musar zu Dewarim 29:4

And our Sages, of blessed memory, said that repentance is not denied to the sinner unless his heart remains evil. But as for him who wants to draw nearer to God, God does not close the gates of repentance before him, but he opens the gates of repentance for him and teaches him the righteous path, as it is said, "Good and upright is the Lord, therefore doth He instruct sinners in the way" (Ps. 25:8). And further, "But from thence ye will seek the Lord thy God; and thou shalt find Him, if thou search after Him with all thy heart and with all thy soul" (Deut. 4:29). And further, "But the word is very nigh unto thee in thy mouth, and in thy heart, that thou mayest do it" (Deut. 30:14). And further, "The Lord is nigh unto all those that call upon Him, to all who call upon Him in truth" (Ps. 145:18).
