Isaiah 40:28 -41:1
In this passage, Isaiah exhorts the people of Israel on who God is, and to wait for, or wait upon, the Lord. It is natural for us to rely on our own power, on our own strength to attempt to accomplish our goals, or overcome the obstacles in our life. Here Isaiah reminds the people that the strength of God is inexhaustible, His understanding has no limits. He is the creator of the universe. No matter how strong we are, or how much endurance we have, there is a limit to our power. There is a breaking point for every human, young or old. Only the Lord has no limits. It is the strength of the Lord, and His power, that will enable us to perform the works of God. God calls all of us to a life that cannot be achieved without Him. We must renew our strength from the bottomless reservoir of God’s power.
Access to God’s strength is revealed in verse 31. “But those that wait for the Lord…” Isaiah says those that WAIT. In a culture of busyness, waiting can seem like a waste of time. However, waiting for someone shows their importance. Often you can see how important someone is on whether people wait for them when starting a meeting or a project. Also, waiting comes with expectation. We wait for the Lord because we expect Him to arrive. In the presence of the Lord there is a renewal of strength that will grant supernatural endurance. In all you do, wait for the Lord.
