We need to add contentment to our godly formation, to subdue all thoughts that can come from unrighteous mammon; to overcome all the pull that can come from what money can do. Christ would then become our life-dominant thought and source of contentment.
And what the gospel of God (or of life everlasting and eternal) is now doing is to perfect our victory over mammon, so we can walk in love with God. A believer who attains the joy of the Father that enables him to consistently despise the god of this world (mammon) is divinely wiser than a believer who hasn’t.
The only way to arrest the influence that mammon exerts upon our soul through the love of money is by being introduced to a contrary influence or knowledge called the Faith of the Son. His freedom lies in a definition of life that is firstly found in Christ and then in the Father, and his reward for finding and keeping these twin expressions of life is a reward called God.
