1 John 1:8-10 NKJV
“If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say that we have not sinned, we make Him a liar, and His word is not in us.”
-Confession must be personal. God looks at the heart of men to transform and mould us according to His will and purpose. As God convicts us of sin that is hindering our fellowship with Him, we must confess it and receive forgiveness and cleansing for our relationship with God to continue without hindrance for His grace is sufficient for us and His power is made perfect in our weakness. King David confessed his sin when he went astay, as he was called a man after God’s own heart even from before his election. Confession brings us to a place of humility before God. Even though we were forgiven through the ultimate sacrifice of Jesus Christ on the cross, it is also the place where we find the mercy, grace, peace and love of Christ. It is a place of victory over sin and death, and declare that we are more than conquorers in Christ Jesus.
Have mercy upon me merciful Savior, according to Your lovingkindness, according to the multitude of Your tender mercies. Blot out my transgressions. Wash me thoroughly from my iniquity, and cleanse me from my sin, for I acknowledge my transgressions, and my sin is always before me. Against You, You only, have I sinned, and done this evil in Your sight, that You may be found just when You speak, and blameless when You judge. Behold, I was brought forth in iniquity, and in sin my mother conceived me. Behold, You desire truth in the inward parts, and in the hidden part You will make me to know wisdom. Purge me with hyssop, and I shall be clean; wash me, and I shall be whiter than snow. Make me hear joy and gladness, that the bones You have broken may rejoice. Hide Your face from my sins, and blot out all my iniquities. Create in me a clean heart, O God, and renew a steadfast spirit within me. Do not cast me away from Your presence, and do not take Your Holy Spirit from me. Restore to me the joy of Your salvation, and uphold me by Your generous Spirit. Then I will teach transgressors Your ways, and sinners shall be converted to You. Deliver me from the guilt of bloodshed, O Lord, the God of my salvation, and my tongue shall sing aloud of Your righteousness. O Lord, open my lips, and my mouth shall show forth Your praise. For You do not desire sacrifice, or else I would give it; You do not delight in burnt offering. The sacrifices of God are a broken spirit, a broken and a contrite heart, these O God, You will not despise. Amen
