If we pursue the desires of our hearts before the kingdom of God and His righteousness, our desires become perverted. Wanting to do things our own way, looking to the earthly things of this world, which is temporary. But if we seek first God’s heavenly kingdom and His righteousness, the desires of our hearts are fulfilled in Him by seeking His way.
Having our hearts steadfast in that which is eternal, and not of the world which is temporary. Looking towards heaven and not the world.
Therefore, everything else is added unto us, because we sought God’s kingdom and His righteousness first. Looking to His way.
