One desiring salvation must always have a heart inclined towards penitence and contrition: “The sacrifices of God are a broken spirit; a broken and a contrite heart, O God, thou wilt not despise” (Ps. 51:19). With such a contrite spirit a person can avoid without trouble all the artful tricks of the devil, whose efforts are all directed towards disturbing the spirit of a person. By this disturbance he sows tares (i.e., weeds), according to the words of the Gospel: “Sir, didst not thou sow good seed in thy field? from whence then hath it tares? He said unto them, ‘An enemy hath done this’” (Mt. 13:27-28). But when a person struggles to have a meek heart and to keep peace in his thoughts, then are all the wiles of the enemy powerless; for, where there is peace of thought, God Himself resides: “In Salem also is his tabernacle, and his dwelling place in Zion” (Ps. 76:2).
We offend the greatness of God with our sinning throughout our entire lives, and so must always humbly ask the Lord forgiveness for our sins.
~St Seraphim of Sarov
