There are four promises, four "wills" here. First, you "will" renew your strength.

"Renew" means to exchange our strength for his, in the sense of trading an old Volkswagen Beetle for a new Ferrari. He will replace our failing strength with his divine, omnipotent power.

Paul heard this God say, "My grace is sufficient for you, for my power is made perfect in weakness" (2 Corinthians 12.9). His grace, his power—not ours. And so Paul could testify: "I have been crucified with Christ and I no longer live, but Christ lives in me. The life I live in the body, I live by faith in the Son of God, who loved me and gave himself for me" (Galatians 2:20). Paul knew about the exchanged life, ours for God’s. His strength, his power, his help, his resources flowing into us and through us. If we don't quit. If we stay connected to this God in trusting worship.

Then we "will" soar on wings like eagles. Sometimes we need God to set us free from our bondage, our failures, our past. And he will.

We "will" run and not grow weary. Sometimes we need God to empower us as we run the race before us, looking unto Jesus, the author and finisher of our faith (Hebrews 12:1-2).

And we "will" walk and not be faint. This is sometimes the hardest thing to do—to keep on going, no matter what happens to us. To walk and not faint, even when we should and even when we want to.

But note this fact: the Lord says that we "will" renew our strength, but he doesn't say when: "Let us not become weary in well doing, for at the proper time we will reap a harvest if we do not give up" (Galatians 6:9).

We may see today God's plan and purpose in this problem and disappointment; we may see it tomorrow. Or we may not see it until we are in glory with our Lord: "Now we see but a poor reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known" (1 Corinthians 13:12).

When Mike Yaconelli and his wife lost their young child, someone asked him how he was doing. He replied, "We're making it day to day, knowing that one day we will be able to ask God some very hard questions."

We have learned that our God is holy, thus deserving of worship brought to him with clean hands and hearts. We have learned that he is forgiving, so that he will cleanse every sin we confess and purify us so that we can worship him. We have learned today that our God is love, so that he will hear every prayer we offer in worship, and meet every need we trust to him according to his will and timing, for his glory and our good.
