Many products come with instructions or warnings which state "Use for intended purpose only". For example, a power drill should not be used as a ear wax cleaner and a blanket shouldn't be used as a parachute. I once used my mom's best fabric scissors to cut up an aluminum can to make a throwing star. I ruined the scissors as they became dull and no longer functional for their intended purpose. My mom was not happy (but the throwing star was sweet). We often ruin others by using our gifts and talents to hurt them instead of help them.
Lord, help me to realize that I have a purpose and I must be careful with how I use the gifts You have given me so that I "sharpen" and not "cut".
