Thank God for the free gift of salvation. Although this gift was free to you and I, the cost to God was priceless. God chose to redeem us not by natural means which will eventually decay, but by the sacrificing His Son - 1 Pe 1:18-19. Jesus was tempted in all ways but found to be without sin - Heb 4:15. Therefore His blood that was shed was spotless, pure and perfect. This what what was needed to take care of all of the sins of humanity.
God made this sacrifice so that you and I can live in dominion as He originally intended - Gen 1:26-28. God restored us back into right standing with Him through the sacrifice of Jesus. Now we are free from every bondage of sin, sickness and lack. Friend you don't have to live in condemnation or guilt any longer. The blood of Jesus took care of it all. If you make a mistake, confess your sins right there and move on. As you develop in your relationship with God and spend time in the Word, you will be empowered to walk in the manifestation of your victory over that sin. Remember you are an overcomer - 1 Jn 5:4.
