SPIRITUAL MIND

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.” But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. For what man knows the things of a man except the spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God. Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God. (1 Cor 2:9-12 NKJV)

HE THAT IS SPIRITUAL" Discerneth all things. There is no limitation upon him in the realm of the things of God. He can "freely" receive the divine revelation and he glories in it. He, too, may enter, as any other man, into the subjects which are common to human knowledge. He discerneth all things; yet he is discerned, or understood by no man. How could it be otherwise since he has "the mind of Christ?

There are two great spiritual changes which are possible to human experience—the change from the "natural" man to the saved man, and the change from the "carnal" man to the " spiritual" man. The "spiritual" man is the divine ideal in life and ministry, in power with God and man, in unbroken fellowship and blessing.
God is waiting for those who are ready to change their lives, Matthew  11:28  Come unto me, all ye that labour and are heavy laden, and I will give you rest.
