Everything created has a purpose. Even when human beings manufacture things, they are always designed for a specific purpose.
As children of God, we all know that the Lord has formed each one of us uniquely for us to display what He has created us for. Isaiah 43: 7 Even every one that is called by my name: for I have created him for my glory, I have formed him; yea, I have made him.
Sacrifice is a step beyond convenience. Bill Johnson
