Human strength always runs out. Verse 30 tells us even the strongest run out of strength. Every human ability is limited. Physical strength, human wisdom, human creativity, emotional energy… all human abilities eventually fail.
Israel’s strength, of even their young men, would fail completely when they were taken away as prisoners to the country of Babylon. But the Lord’s strength will never fail, and He would restore them and bring them back from Babylon, just like He promised.
Our strength fails, but strength will rise for those who wait on the Lord.
Waiting on the Lord involves both faith and patience. Faith is trusting God to work, and expressing that trust in prayer and thanksgiving and a quiet confidence.
Patience is trusting God to act in His time and not getting agitated or anxious. Anxiety and fear take our strength away. Sometimes we can be tempted to use our own actions to try and get a breakthrough. This also takes our strength away.
But patience, prayer and praise, as we wait for Him, means that we will have our strength renewed.
“In returning and rest you shall be saved; in quietness and trust shall be your strength.” (Isaiah 30:15)
Can I encourage you today to rest your heart and mind on Him? Wait for Him. He is faithful.
