Christians are to reject all that produces a sense of worthlessness as contrary to God's loving concern for us. Therefore to love oneself in the proper way is not the same as selfishness. In other words, God wants us to see our condition and our potentials as He sees them. The Christian faith affirms our integrity and value as persons. For one thing, death is the sentence God passes upon sin that destroys us as individuals.
Sin is the most deadly poison ever to invade our world and our lives.
Therefore God seeks to bring about the end of sin. We are to die to sin itself. Sin in all its forms is not something to be trifled with.
