We can be tired, weary and emotionally distraught, but after spending time alone with God, we find that He injects into our bodies energy, power and strength.
You can't tell a woman who is called by God to teach that she cannot teach the Word of God... So I think the distinction is that there's a difference between the authority of a pastor and a Bible teacher.
I'm convinced that the man who has learned to meditate upon the Lord will be able to run on his feet and walk in his spirit. Although he may be hurried by his vocation, that's not the issue. The issue is how fast his spirit is going. To slow it down takes a period of time.
If the Lord says to give more than you think you are able to give, know that He will provide for you. Whether things are sailing smoothly or the bottom has dropped out, He is always trustworthy. You can count on Almighty God to keep His everlasting Word.
