Your update is encouraging and it is good that you are asking for wisdom as you prepare for this hearing. Having a documented violation for false statements is a piece of knowledge, a fact that can be presented, but knowledge alone only gives you facts. Wisdom is what teaches you how to use those facts rightly, with prudence, discretion, and sound judgment.
Scripture teaches that wisdom is far more valuable than riches or even than winning a case, and that nothing we desire can compare with it. The fear of the Lord is the beginning of wisdom, which means wisdom starts with reverence for God and a hatred for evil, and with a desire to walk in His ways rather than simply to prevail. When wisdom is personified in Proverbs, it speaks as one who dwells with prudence, who holds counsel and sound understanding and strength, and by whom kings reign and judges decree justice. In Christ are hidden all the treasures of wisdom and knowledge, so to seek wisdom is to seek Him.
The purpose of wisdom described in Proverbs is to give instruction in righteousness, justice, judgment and equity, to give subtlety to the simple and discretion to the young, and to cause the wise to increase in learning. That is exactly what you need in this hearing, not only evidence but the ability to present it truthfully, calmly and fairly, without strife or manipulation.
There is a wisdom that comes from the world that is earthly and self serving and leads to envy and conflict, and God calls that foolishness. The wisdom that comes from above is different. It is pure, peaceable, and it produces a life marked by integrity. It is a defense, better than money alone, because it gives life to those who have it. It is the principal thing to seek, and with all your getting you are urged to get understanding.
So in this situation pray that God will give you that higher wisdom. Ask Him for a word of wisdom for the specific moment, for the right words, the right timing, and the right spirit. He promises to give wisdom generously to those who ask and who seek Him early because He loves those who love Him. Pray that He will guide you to act with honesty and prudence, to speak with clarity and self control, and to trust Him with the outcome, knowing that He oversees all matters of justice.
May the Lord grant you counsel and sound wisdom for this hearing, guard your heart from anxiety and from any desire to use this evidence harshly, and help you to handle everything with justice and equity. May He give you discretion in what to say and what not to say, strength to remain calm, and peace in trusting that He is the one who establishes true justice. I pray that as you seek Him, He will pour out His Spirit of wisdom and understanding upon you and lead you step by step in Jesus name.
