Do you feed your faith day by day with the promises of this triumphant gospel?
Do you, as a believer, go to the gospel day by day and savor its power in verses like Romans 8:32, “He who did not spare his own Son, but delivered him over for us all, how will he not also with him freely give us all things?”

The gospel is the good news that God gave us his son, so as to obtain for us everything that would be good for us. Therefore the gospel is the power that gives us victory over temptation to despair and to pride and to greed and to lust. The gospel alone can triumph over every obstacle and bring us to eternal joy. Whatever it costs, stand in it, hold it fast, believe on it, feed on it, savor it, count it more precious than silver or gold. The gospel will save you. And it alone.

Do not give up when waiting on God seems endless.

Even youths shall faint and be weary, and young men shall fall exhausted; but they who wait for the Lord shall renew their strength; they shall mount up with wings like eagles; they shall run and not be weary; they shall walk and not faint. (Isaiah 40:30–31)

“Here is a call for the endurance of the saints” (Revelation 14:12).

We all long for rest and refreshment. That’s a God-given longing that he promises to fulfill: “I will satisfy the weary soul, and every languishing soul I will replenish” (Jeremiah 31:25).

And in a very real way Jesus gives rest to “all who labor and are heavy laden” and come to him (Matthew 11:28). But in this age, it is not the complete rest.

In this age, Jesus grants us the gospel rest of ceasing the impossible labor of self-atonement for our sins (2 Corinthians 5:21). But in embracing the gospel we find ourselves also drafted into a war — a war to keep believing the gospel and a war to spread it to others. In this age we “strive to enter that [complete] rest” of the age to come (Hebrews 4:11).

And wars are exhausting — especially long ones. That’s why you are often tired. Most soldiers who experience the fierceness of combat want to get out of it. That’s why you feel urges to escape or surrender. That’s why there are times you’re tempted to give up.

But don’t give up. No, rather “take courage! Do not let your hands be weak, for your work shall be rewarded” (2 Chronicles 15:7).

Jerusalem shall be inhabited as villages without walls, because of the multitude of people and livestock in it. And I will be to her a wall of fire all around, declares the Lord, and I will be the glory in her midst. (Zechariah 2:4–5)
