Walk and do not grow weary.
Even the youths shall faint and be weary, and the young men shall utterly fall, but those who wait on the Lord renew their strength; they shall mount up with wings like eagles, they shall run and not be weary, they shall walk and not faint.
He works in His time. The strength of men is small in comparison to the strength and the resources of God.
Be patient and stay close to Him and trust He is at work for your benefit. In His time, you will see blessing and until then you will find His strength will sustain you.
