This one thing would change most of what we call “church-life”.
Most organizational churches are consumed with “busy-ness” thinking they are “hitting a lick for God”.
If we would begin here…
“But seek first His kingdom and His righteousness, and all these things will be added to you.”
You noted the first word - “but”.
The context is worry, fretting over housing, clothing, food and the like.
Jesus is telling us to pursue something else.
When we pursue the Kingdom we will be free…
“So do not worry about tomorrow; for tomorrow will care for itself.
Each day has enough trouble of its own.”
How do we pursue the Kingdom?
First, one must be truly saved.
Not just religious.
Not just aware of the Truth of the Lord.
Truly born again.
Then, one must abide in the Lord.
A good definition of “sin” is “stepping outside the abiding of the Lord”.
If we abide in Him we will not sin.
“Abide in Me, and I in you. As the branch cannot bear fruit of itself unless it abides in the vine, so neither can you unless you abide in Me.
“If anyone does not abide in Me, he is thrown away as a branch and dries up; and they gather them, and cast them into the fire and they are burned.
“If you abide in Me, and My words abide in you, ask whatever you wish, and it will be done for you.
“Just as the Father has loved Me, I have also loved you; abide in My love.
“If you keep My commandments, you will abide in My love; just as I have kept My Father's commandments and abide in His love.
Pursue the Kingdom.
Abide in the Lord.
Watch what happens…
