Isa40:27 Why do you say, I Jacob, and assert, O Israel, My way is hidden from the Lord,
31 Yet those who wait for the Lord will gain new strength; They will mount up with wings like eagles, They will run and not get tired, They will walk and not become weary.
When we're in our own ways, in the things that we plan for ourselves, we can grow weary and tired, stumble badly.
But if we find the callings of God in our lives, find this one thing that God has designed and created us to do, find the way that God had intended for us to walk on, when we wait for the Lord, depend on His wisdom and guidance instead of our own, we will gain new strength.
"wait for the Lord" can sound simple, but it can mean 40 years for Moses in the desert, 40 days for Jesus to be tempted, 25 years for Abraham before Sarah had the baby... but if we do wait, and when God does show up, we'll find supernatural strength, energy and joy to do the things that're impossible.
Ps119:81 My soul languishes for Your salvation; I wait for your word.
89 Forever, O lord, Your word is settled in heaven.
90 Your faithfulness continues throughtout all generations.
92 If your law had not been my delight, then I would have perished in my affliction.
96 I have seen a limit to all perfection;
Your commandment is exceedingly broad.
Sometimes the word of God can look to us like a limit. We're so tempted to break that limit and act in out own ways. For David, he'd always struggle to fight back with his enemy in his own power. But he didn't break that limit. He sticked with the law. And within that limit he found out later that God's commandment is exceedlingly broad. The limit to us is no limit to God. If we keep the limit that God has put in our lives, we will actually find ourselves into realm that "God will make His commandment exceedingly broad."
