and every tongue confess that Jesus Christ is Lord, to the glory of God the Father. (Philippians 2:11, ESV)As the knees bow... the tongues will confess that Jesus Christ is Lord.
Let's not forget the context of this verse though. The Apostle is encouraging us to be humbly obedient. He has told us to put others ahead of ourselves and too look to their needs, not just our own. He tells us to do this the way Jesus did... to have his mind... his thought process. And then after he describes the great lengths Jesus went to in order to be obedient to the Father, he tells us this: Christ was and will be glorified.
To help us to think beyond as well. To think past this life. Yes, Jesus suffered the cross and the humiliation. Yes he endured as a man, but he also knew the end result. God would be glorified and he would be lifted up.
If you are looking for motivation or encouragement to continue, then consider the end and your final state.
