To be joyful is a decision we must make each day. Paul knew what it was like to be joyful in the face of adversity. We can have joy at ALL times simply because we know and trust Jesus. If we allow the enemy to rob us of our joy, we allow him to rob of us our strength. We grow weary, depressed and the children suffer, too.
Teaching becomes a chore instead of a privilege and learning becomes dull and dreary for all.
He will bless the homeschooling and discipling of our children. Our own strength and wisdom will always fall short but God's strength and wisdom will never fail. Someone once described faith as simply believing God will do what He said He would do in His Word. Look to God to provide these answers and direct your steps. He has already purchased all of this for you through His shed blood on the cross.
