Man must spend his strength on things that matter. In doing so, we must focus our efforts upon the right things while working through and by God's power.
Scripture provides examples of specific sins; however, no example DEFINES sin. John's first epistle defines it as the transgression of the law.
Do you want God's respect? The Lord said, “to this man will I look, even to him that is poor and of a contrite spirit, and trembleth at my word.”
