1 Corinthians 9:26 (a) This refers to the actions of one who wastes his life in busy idleness or in useless, fruitless endeavor.
Ephesians 2:2 (a) Here is meant the space between Heaven and earth through which the prayers of GOD's people must pass, and through which the saints must go on their way home to GOD. The Spirit of GOD must take our prayers through the opposition of evil spirits up to the Throne of GOD and the Lord JESUS. Eventually the mighty power of GOD must take the spirits of His people through all Satanic opposition and bring them safe home to GOD.
