If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself

John 7:17

And beside this, giving all diligence,
add to your faith virtue;
and to virtue knowledge;
and to knowledge temperance;
and to temperance patience;
and to patience godliness;
and to godliness brotherly kindness;
and to brotherly kindness charity.
For if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ.

2 Peter 1:5-8 KJV
