Unlimited is having an infinite number of solutions while source is to obtain something from a particular place, person or thing.
But as it is written: “Eye has not seen, nor ear heard, Nor have entered into the heart of man The things which God has prepared for those who love Him.” I Corinthians 2:9 NKJV
Ears have heard the wealth and glory of King Solomon, Eyes have seen and still seeing the Riches in the hands of the Richest Man in the world “Jeff Bezos”.
But the Lord is saying today, “despite all you think you’ve heard or seen, because you love me, I have prepared things unthinkable, immeasurable, and unlimited.”
God has called us to UNLIMITED RESOURCES: Power, Riches, Wisdom… Rev. 5:12 NKJV.
