“But rise, and stand upon thy feet: for I have appeared unto thee for this purpose, to make thee a minister and a witness both of these things which thou hast seen, and of those things in the which I will appear unto thee;” Acts 26:16
God said He will make Paul a minister. Bible College can’t do that, studying to show yourself approved can’t do that, someone laying their hands on you and ordaining you can’t do that. Though these things may offer some help, it is God who calls and makes ministers.
