Romans 15:13-17 Now may the God of hope fill you with all joy and peace in believing, that you may abound in hope by the power of the Holy Spirit. Now I myself am confident concerning you, my brethren, that you also are full of goodness, filled with all knowledge, able also to admonish one another. Nevertheless, brethren, I have written more boldly to you on some points, as reminding you, because of the grace given to me by God, that I might be a minister of Jesus Christ to the Gentiles, ministering the gospel of God, that the offering of the Gentiles might be acceptable, sanctified by the Holy Spirit. Therefore I have reason to glory in Christ Jesus in the things which pertain to God.
1 Corinthians 2:9b-14 “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. These things we also speak, not in words which man’s wisdom teaches but which the Holy Spirit teaches, comparing spiritual things with spiritual. But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned.
