WHAT THE KINGDOM OF GOD IS NOT
Contrary to much of what we hear, the Kingdom of God is not in word.
“For the kingdom of God
is not in word, but in power”
1 Corinthians 4:20
May God help us to see that the Kingdom of God does not lie in teachings, doctrines and messages; it has very little to do with such. It is a Kingdom of Power, Substance and Reality. There is nothing ethereal, unsubstantive, or virtual about its existence. Those who consider it to be an intellectual message or concept are deceived and do not understand the truth of it. The Kingdom of God is known by the power it wields over its subjects. It is revealed within the lives of those who are growing and developing in the life and wonder of the Lordship of Jesus Christ. Obedience is the dominant expression of a heart in pursuit of its reality. The Kingdom of God speaks of the Lordship and Reign of Christ; wherever He reigns is where His Kingdom is coming to be.
“And why call ye me, Lord, Lord,
and do not the things which I say?”
Luke 6:46
How can we speak of the Kingdom of God without this fundamental truth? Obedience is the underlying principle of His Kingdom. In our day of an antinomian gospel we speak of a “kingdom” in which we simply confess He is Lord and then live our lives as we see fit and expect to have access to His Kingdom promises! It is a staggering and bewildering concept.
“Blessed are they that do his commandments,
that they may have right to the tree of life,
and may enter in through the gates into the city”
Revelation 22:14
It is not enough to know His commandments; the entering into this magnificent City is based solely on the doing of His commandments. His Word is clear and unmistakable. Let these words ring within the sanctum of our own hearts; meditate and hold all our actions to this one great rule of the Kingdom:
“Blessed are they that DO His commandments…”
“To be continued…”

You could also say, obedience is better than words or obedience is more powerful than words.
The Presence of God is more powerful than words.
