16 Jesus answered them and said, “My doctrine is not Mine, but His who sent Me. 17 If anyone wills to do His will, he shall know concerning the doctrine, whether it is from God or whether I speak on My own authority.” (John 7:16-17)
Jesus made the bold claim that He taught the word and will of God. He explained how you can know His message is from God. First, you must have a determination to do God’s will (“if anyone wills to do His will”). When you do not want to do the will of God you will not accept what Jesus said as the word of God. But, if you earnestly want to do God’s will, Jesus said you can and will understand His teaching and its heavenly authority (“he shall know concerning the doctrine”). Understanding the Bible has much to do with the attitude you have when you read it or hear it taught. A hard heart refuses it, but a heart that wants to do God’s will receives the word of Christ. Jesus has spoken God’s will with heaven’s authority. Do you want to do God’s will? If so, then you can understand His teaching.
