Although it satisfies the intellect, the Gospel is not an intellectual one.
The more one knows the Lord, the simpler it gets. The simpler it gets, the deeper the work.
In high school I went to a tiny little Texas church that was two blocks from my house. There was a mentally retarded woman who went to every meeting, including prayer meetings. She also had a cleft palate. Her name was Shirley. Shirley drove me crazy and it was probably because she was the only person in the church who knew I was not saved. When we divided up for the prayer meeting, she always wanted to be in the group with me. As difficult as it was for her to speak, Shirley went after me over and over and over again.
It was only when I gave my life to the Lord fourteen years later that I could see the Lord had used Shirley to confront me. The longer I know Him, the more I appreciate Shirley's availability to Him.
The Servant does not need to feel smart, experienced or equipped.
He only needs to be available.
Those who are truly available are trained in the exercising of faith. They can be trusted in areas where few are allowed. They are willing to tackle tough studies or to take on a project that has not been done before. They can be sent without first knowing what they must do upon arrival.
They understand God's anointing.
They have crossed The Line.
The Creator of the universe did not come as a genius.
He came as a Savior.
