As we contemplate before our confession, we need to make sure that God’s kingdom which is the center teachings of our Lord Jesus Christ will not be compromised. Those who received true conversion can testify their repentance by confessing their sins. Peter said “Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins.” Positive confession is good. But deceptive proclamation such as “I follow God’s will”, "I am an obedient child of God““I am wealthy because I give my 10 %," is deceptive in nature; as far as reward is concerned, maybe the intention is to encourage others to do the same for own personal gain, or to lift himself as a high giver. Confessing about other people’s deeds or success could be harmful and might fall to gossip and lead to division. Sometimes positive intention has a drawback.
Negative confession will not always lead to negative blessings. Jesus said “He went a little farther and fell on His face, and prayed, saying, “O My Father, if it is possible, let this cup pass from Me; nevertheless, not as I will, but as You will.” (Matthew 26:39 -NKJV) “Cast your burden on the Lord, And He shall sustain you; He shall never permit the righteous to be moved.” (Psalm 55:22- NJKV)
If you have personal relationship with Jesus Christ, talk to Him and confess all your unrighteousness and all your sins will be wiped out. With contrite heart you will feel the forgiveness.
“If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.” 1 John 1:9 (NKJV)
