If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself. ( John 7: 17)
Life is our school, God is our teacher. Walk with him, talk with him, learn from him and you will have all you need to join Him in heaven.
Believe God can explain your problems and difficulties, it is all part of his plan for your life. He will explain it better than any human can. Turn to the teacher.
