Hearing the voice of God and obeying it is the key to promotion. Many years ago I heard Kenneth Hagin say that one of the most important factors in bringing him to where he was in the ministry was the ability to hear the voice of God and to be led by the Spirit of God.
After being in the ministry for some years, I fully agree with that statement. I believe that the single greatest factor that leads to promotion in ministry is your ability to hear the voice of God. Read it for yourself; this is not implied, it is stated explicitly in the Bible.
“And it shall come to pass, if thou shalt hearken diligently unto the voice of the LORD thy God, to observe and to do all his commandments which I command thee this day, that the LORD thy God will set thee on high above all nations of the earth:” Deuteronomy 28:1
