2 Corinthians 8:7 Therefore, as ye abound in every thing, in faith, and utterance, and knowledge, and in all diligence, and in your love to us, see that ye abound in this grace also.
2 Peter 1:5 And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge;
Titus 1:1 Paul, a bond-servant of God and an apostle of Jesus Christ, for the faith of those chosen of God and the knowledge of the truth which is according to godliness,
If faith opens the eyes of the heart, understanding supports wisdom and knowledge. But without faith, there is no understanding even when there is knowledge. Wisdom will guide the faithful heart in the acquisition and application of appropriate knowledge.
By wisdom a house is built,
And by understanding it is established;
And by knowledge the rooms are filled
With all precious and pleasant riches. (Prov 24:3,4)
