God never lets you down and there is no exception to His Truth. He wants to make a difference in your life if you will let Him. Obey Him and see what He can do for you.
A pure heart and good conscience are evident when one walks closely with God. Live out these truths, listen to the Holy Spirit and always ask God to forgive you immediately when you fall out of line.
Do everything in life with enthusiasm for the Lord. Enthusiasm is catching, but so is grumbling. Commit your tasks to God, pray over them and He will bless you in the process.
