My teaching is not Mine but His who sent Me.
If anyone is willing to do His will, he will know of the teaching, whether it is of God or whether I speak from Myself.
He who speaks from himself seeks his own glory; but He who is seeking the glory of the One who sent Him, He is true, and there is no unrighteousness in Him.
This is Jesus speaking as recorded in John’s gospel chapter 7:16-18.
Many people seem to have a problem knowing what God’s will is for their lives. I’m not one of them. For me the problem has not been not knowing but not being willing to do what I know He wants me to do.
But as Jesus says above, the reality is that if you really want to know what God is saying you have to be willing to do His will. This truth applies whether you are in prayer listening to the Holy Spirit or whether you are listening to someone preaching. Or whether you are reading a blog from some obscure Irish man who seems to think he can teach you a thing or two about being a disciple.
