I became a self-reliant leader over time, and in so doing, I was dependent upon limited resources. I had not really learned to rely on God and others.
The self-reliant leader is, first, not dependent upon the Holy Spirit. In his book Lion and Lamb, Brennan Manning wrote, "How vast are the resources of His power open to us who believe in Him!" This self-reliant leader is not resembling the gospel of Jesus Christ which has said all of this vast power of God has been available to you to depend upon.
Secondly, the self-reliant leader relies on limited resources in his lack of dependence upon others. Self-reliant leaders lead in isolation from others, and pride is the reason for all our isolation. Often those who lead alone find an interesting resistance in their heart and lfie. Perhaps they blame it on Satan, but that resistance is not Satan; it is God. For "God resists the proud, and he lifts up the humble." (James 4:6)
Great leaders are not self-reliant. They learn to rely wholly on God and also on others for strength.
