"Busyness is not Godliness. God is not impressed with your production capacity as much as He is concerned that the product of your home--your own children--be chiseled and molded and perfected to the best of your ability. You may tire of this mundane task, but the Lord admonishes you not to grow weary and promises to supply the energy and strength as needed in this all-important task (Isaiah 40:28-31). God's strength is for what He plans for you to do--not stamina for everything you might want to do."
Do not grow weary in doing good - Keep on keeping on - Seek first His kingdom and His righteousness and all these things will be added to you.
