Every task (mission) in Life will require you to: Press On

Gal 6:9 Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up.

Breakthrough will COME as we PRESS ON 

The end of a matter is better than its beginning, and patience is better than pride.  Ecc 7:8

Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles. And let us run with perseverance the race marked out for us, fixing our eyes on Jesus, the pioneer and perfecter of faith. For the joy set before him he endured the cross, scorning its shame, and sat down at the right hand of the throne of God. Consider him who endured such opposition from sinners, so that you will not grow weary and lose heart.  Heb 12:1-3

4 things that will help us PRESS ON:
1. Look at the greats
v1a: "...We are surrounded by such a great cloud of witnesses..."
And you should imitate me, just as I imitate Christ. 1. Cor 11:1

2. Look at yourself
v1b: "...let us throw off everything that hinders and the sin that so easily entangles."
I discipline my body like an athlete, training it to do what it should. Otherwise, I fear that after preaching to others I myself might be disqualified. 1 Cor 9:27

3. Look to the end
I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus. Phil 3:14

4. Fix your eyes at Jesus
v2: "...fixing our eyes on Jesus, the pioneer and perfecter of faith. For the joy set before him he endured the cross, scorning its shame, and sat down at the right hand of the throne of God."
Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me. John 15:4

Shift your focus and experience a breakthrough as you press on.
