The chief end of man is to glorify God by enjoying Him forever.
We were made for God. To have fellowship with Him. To enjoy the good things from His hand, To praise Him, To bask in His glory. We were designed for God. We are most happy when we are doing and being what God created us to do and be...We are in a word, "happified." How worthy is heaven that your life should be wholly spent as a journey towards it? To what better purpose can you spend your life? How can you better employ your strength, use your means, and spend your days, than in traveling the road that leads to the everlasting enjoyment of God, to His glorious presence? Jonathan Edwards
17 " Sanctify them in the truth; Your word is truth. 18 "As You sent Me into the world, I also have sent them into the world. 19 "For their sakes I sanctify Myself, that they themselves also may be sanctified in truth.
