Many Christians feel that walking by the Spirit is very difficult. My pastor, Dr. Lester Sumrall used to say, "God cannot bless ignorance. If God's Holy Spirit is to function fully in our lives, we must have an open heart and a consuming desire to know all we can about the nature and role of the Holy Spirit." Even though our flesh (our sin nature) and the Holy Spirit are opposing forces in constant conflict, God initiated powerful strategies to enable us to walk by the Spirit and dominate the sin nature.
