St Isaac the Syrian: This is how many God-fearing people think...

“Will God, if I ask, forgive me these things by which I am pained and by whose memory I am tormented, things by which, though I abhor them, I go on backsliding? Yet after they have taken place the pain they give me is even greater than that of a scorpion's sting. Though I abhor them, I am still in the middle of them, and when I repent of them with suffering I wretchedly return to them again.”

This is how many God-fearing people think, people who foster virtue and are pricked with the suffering of compunction, who mourn over their sin; yet human prosperity compels them to bear with the backsliding which results from it. They live between sin and repentance all the time. Let us not be in doubt, O fellow humanity, concerning the hope of our salvation, seeing that the One who bore sufferings for our sakes is very concerned about our salvation; God's mercifulness is far more extensive than we can conceive, God's grace is greater than what we ask for.
