Jesus said something in vs 4

I have glorified You [down here] on the earth by completing the work that You gave Me to do.

So, doing the work God gave to you is the only way to glorify Him. And the work can't be done without knowing your purpose on earth.

Most people live a life void of purpose and their lives don't bring glory to God, it also leads to emptiness and frustration on earth.

See vs 5

Now, Father, glorify Me together with Yourself, with the glory and majesty that I had with You before the world existed.

So it invariably means that your glorification on earth is tied to fulfilling of purpose. Little wonder most folks struggle in life because GOD WILL NOT SPONSOR WHAT HE DIDN'T COMMISSION.

Discover purpose
Pursue it
Then glorification is inevitable

God bless us
