Even money, “dedicated” to the Lord becomes an important factor in Christ’s development of His spiritual kingdom. Anything which can, or can be made to have, a spiritual purpose can be seen to be part of Christ’s spiritual Kingdom. When Christ said, “My kingdom is not of this world“, He had no more thought of excluding physical things and political and social-family relationships than when He said to His disciples “ye are not of this world” (the Greek phrase is identical).
