Isaiah 40:29 He gives strength to the weary and increases the power of the weak.
If we want to be able to win a race or a competition, we must train for it and get ourselves ready.
But training by yourself can be very hard work – it is always better when we have a coach who will continue to encourage us every step of the way.
God continues to be our coach – if we want to be ready for the race, we need to listen to our coach and obey Him!
