1 Corinthians 2:9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
In our wildest imagination, we cannot come up with the wonderful things the Lord has stored up for us. When Paul says it is written he means in the book of Isaiah it says what this first verse says. The words from Isaiah refer to the wisdom God has prepared for believers. God’s truth is not discover-able by eye or ear nor is it discovered by the mind . The Holy Spirit that we receive is the earnest of greater things to come. God reveals to us what we need to know by way of the Holy Spirit. The Spirit alone was qualified because He knows all that God knows, Himself being God. This is saying we really need to be close enough to God so that when the Holy Spirit has something for us we are ready to receive it and we take and apply it to our lives to do the will of God.
