According to Proverbs 4:23, we are the ones responsible for what is in our heart. It says, “Keep your heart with all diligence, for out of it spring the issues of life.” Psalm 119:11 says, “Your word I have hidden in my heart, that I might not sin against You.”
Psalm 66:18 says, “If I regard iniquity in my heart, the Lord will not hear.” Proverbs 28:13 says, “He who covers his sins will not prosper, but whoever confesses and forsakes them will have mercy.”
Matthew 18:21-35 is the parable of the unforgiving servant. Though he was forgiven a great debt (like us) he refused to forgive others as he was forgiven. Verse 34 says that he was turned over to the torturers.
Verse 35 applies to us as well. It says, “So My heavenly Father also will do to you if each of you, from his heart, does not forgive his brother his trespasses.” The buried unforgiveness is satan’s domain. It opposes God’s way to forgive AS we have been forgiven.
The truth that we need to acknowledge and live by is this. The one who sinned against us? Jesus bore their sins also. He paid the full penalty for our sins as well as the sins they did against us. We opposed God’s way when we buried unforgiveness in our hearts~leaving emotional hooks.
