Morley in his book, I Surrender, stated that the Church's integrity problem lies in her misconception that, â€œWe can add Christ to our lives, but not subtract sin. It is a change in belief without a change in behaviour. It is revival without reformation and without repentance.â€ This illusion has over the years influenced the lifestyle of many who claim to be Christians. A Christian is a saint; he has invited Jesus into his heart, and he cannot harbour sin in it. Our text says that Christians, youths inclusive, have crucified the flesh with the affections and lusts. If you are a saint, your heart must be pure always, free from the love of the world, lust of the flesh and the pride of life. There is no more room for envy, strife and hatred. Instead, there is love, joy, peace and other components of the fruit of the Spirit. To maintain a holy heart, feed on God's word, pray without ceasing, avoid all appearances of evil, and live with heaven in view.
