There is nothing wrong or unnatural with feeling weary . . . (Source unknown)

The thought continues: “. . . but there is everything wrong with abandoning ship in the midst of the fight.” Is fatigue a sufficient reason for quitting? We do get tired when we exert effort over a period of time. And we do need time to recuperate. But when is the right time to stop? Surely, not when the battle is hard, and your help is needed. Pray for strength to continue working with others in the struggle.

Then Jesus said, “Come to me, all of you who are weary and carry heavy burdens, and I will give you rest (Matthew 11:28).
