Confessing sins before God is to admit that you’ve done evil in His sight by seeking His forgiveness. But, the most important aspect about confessing sins has to do with what we do later, so this is where repentance comes heavily into play. Because our post-attitude toward a particular sin that we’ve confessed before God determines if we were sincere during the confession.
The main problem is that lot of times we act just like we had never made any confession to God by keeping on doing the same old things we’ve been doing all along. Living in such way then places ourselves into a state before God in which we cannot receive His blessings since God doesn’t reward rebellion.
Because it’s one thing to ask God to bless you; however, it’s something entirely different to actually place yourself in a receiving state by being obedient to God. Lot of times we pray God to bless us, but when God is about to bless us, He then finds ourselves meddling with sin, which is tantamount to us turning our back on Him by going back in the same sinful things that we had already confessed to Him.
Living For Jesus Christ Alone 
Amen! As God has made perfectly clear in His Word, the Bible, repentance is turning from sin and turning towards righteousness. Or another way to say it is we stop doing the sin we once adored and start doing the godliness that we once spurned. God bless us.
And when we were all fallen to the earth, I heard a voice speaking unto me, and saying in the Hebrew tongue, Saul, Saul, why persecutest thou me? it is hard for thee to kick against the pricks. And I said, Who art thou, Lord? And he said, I am Jesus whom thou persecutest. But rise, and stand upon thy feet: for I have appeared unto thee for this purpose, to make thee a minister and a witness both of these things which thou hast seen, and of those things in the which I will appear unto thee; Delivering thee from the people, and from the Gentiles, unto whom now I send thee, To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me. Whereupon, O king Agrippa, I was not disobedient unto the heavenly vision: But shewed first unto them of Damascus, and at Jerusalem, and throughout all the coasts of Judaea, and then to the Gentiles, that they should repent and turn to God, and do works meet for repentance. Acts 26:14-20
