The joy of the Lord which comes from constant fellowship and communion with Him is the cure for worldliness.
Beneath the facade, a worldly person (believer or not) is a deeply sorrowful person. Man, by design, is held captive by things that bring joy to the soul. The powers of darkness, through this sophisticated machinery called ‘the world’, generates sorrow in the souls of men by creating discontentment and fanning the flame of desire. Meanwhile, these invisible forces, intelligently, design and prescribe worldly elements that appear to supply the kind of joy the soul, through worldly sorrow, has learned to desire. These impotent joys will ever leave greater depths of sorrow in the soul, and without divine intervention, will keep a person in constant pursuit of the world.
But when a person begins to practice constant fellowship with God, through the Holy Spirit, he begins to discover a different kind of joy that all the goodies in the world cannot provide. As fellowship becomes richer, this potent joy then begins to minister strength to the soul to resist the seduction and prescriptions of the world. Psalm 46:4 says “There is a river whose streams make glad the city of God”. These endless streams of joy flow from the the place of fellowship in the Spirit. You cannot overcome the world without it. If you are reading this, God is calling you today into deeper communion with Him.
“Ho! Everyone who thirsts, come to the waters; and you who have no money, come, buy and eat. Yes, come, buy wine and milk without money and without price. Why do you spend money for what is not bread, and your wages for what does not satisfy? Listen carefully to Me, and eat what is good, and let your soul delight itself in abundance”. – Isaiah 55:1-2.
