If you judge yourself – that means, you admit your sin truly before God here in time, you can taste forgiveness in this light. God’s Word says: “If we judge ourselves, God is so good and just to forgive us our sins.”
People can overcome sin neither by means of psychology, nor by modern theologies, nor by oriental meditations… The victory depends on our deep communion with Christ. The essential thing is to be in Christ Jesus, our Lord, by faith. It means that in the particular present moment I am in Him not only passively but at that moment I love Him with all my heart, with all my soul and with all my strength.
To love Him means to offer Him my spiritual powers – heart = emotions, soul = powers of the soul, i.e. memory and reason, as well as my members. To love Him with all my strength means to give Him my will.
