Someone has said, “a belief is what you hold; a conviction is what holds you.” A conviction is not truly a conviction unless it includes a commitment to live by what we claim to believe. A commitment is not a vow but a resolution – a determined purpose to live by God’s word as He applies it to our lives. First we need a commitment to holiness as a total way of life. We must decide that holiness is so important to God that it deserves priority attention in our lives. We must commit ourselves to obeying God in all of his commands. We cannot pick and choose according to our own values. An unforgiving spirit towards someone else is sin just as much as murder. All sin is offensive to God. The measure of sin is not just in its effect upon our neighbor, but in its affront to the majesty and holiness of a sovereign God.
Sin is serious to God, and it becomes serious business to us when we reflect upon the fact that every sin, regardless of how seemingly insignificant it appears to us, is an expression of contempt towards the sovereign authority of God.
