He gives strength to the weary and increases the power of the weak. Isaiah 40:29 NIV
Our God does not faint or get weary. Whatever we need, He is able to supply them all. Those who recognize their own frailties and shortcomings can come to their Heavenly Father and all their needs will be supplied. God hears those who cry out to Him when they feel their weakness. It is through our weakness that God’s strength is made perfect.
But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me. 2 Corinthians 12:9 NIV
