“Though youths grow weary and tired, And vigorous young men stumble badly, Yet those who wait for the Lord Will gain new strength;” Isaiah 40:30-31a ( NASB)
From the book written by the prophet Isaiah we find words of encouragement and promise today. These verses are really about two different kinds of strength which are often very closely related. We realize that there is an inner strength which affects a person's physical strength. So, what the prophet reminds us about in this passage is that this inner strength comes from trusting in the Lord and it affects our ability to perform useful functions in life. Waiting on the Lord is actually an act of trust, of hoping with the expectation that God will act for us according to His promises. God knows when we have an attitude of expectation and He responds by strengthening us. It is new strength because it comes from Him and it comes from trusting in His word – that is what hoping and waiting is all about. And, it is about what God promises to do for us when we wait for Him to act.
