Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart: So shalt thou find favour and good understanding in the sight of God and man.
Hear, ye children, the instruction of a father, and attend to know understanding. For I give you good doctrine, forsake ye not my law.
Get wisdom, get understanding: forget it not; neither decline from the words of my mouth. Forsake her not, and she shall preserve thee: love her, and she shall keep thee.
Enter not into the path of the wicked, and go not in the way of evil men. Avoid it, pass not by it, turn from it, and pass away.
But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
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.
1 Corinthians 2:9
And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ.
1 Corinthians 3:1
