You only have one life to live. Eventualy your time on earth will be done. God has promised all believers that He will bless us with long life. However our time on earth is not infinite.
God, the one who gave you that life, sent you here in an assignment. This assignment is to be completed during your time on earth. While you still have the opportunity to, you must work on completing that assignment and fulfill your purpose.
Don't waste this opportunity. Make a conscious decision to live on purpose.
