Now, the question is, should Christ-followers be celebrating the juror’s decision in the Kyle Rittenhouse as Justice? I would suggest biblical justice was not served and we should lament this fact.
If your enemy is hungry, give him bread to eat,
and if he is thirsty, give him water to drink,
for you will heap burning coals on his head,
and the LORD will reward you. Proverbs 25:21-22
But I say to you, Do not resist the one who is evil. But if anyone slaps you on the right cheek, turn to him the other also. Matthew 5:39
Repay no one evil for evil, but give thought to do what is honorable in the sight of all. If possible, so far as it depends on you, live peaceably with all. Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, “Vengeance is mine, I will repay, says the Lord.” To the contrary, “if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing you will heap burning coals on his head.” Do not be overcome by evil, but overcome evil with good. Romans 12:17-21
I would argue we are required to accept the verdict reached by the jurors, but we should not be celebrating the boy’s innocence. Kingdom purpose would seem to be better served by lamenting with and praying for all those impacted by these acts of violence perpetrated against other image-bearers.
“The Bible never forbids self-defense, and believers are allowed to defend themselves and their families. But the fact that we are permitted to defend ourselves does not necessarily mean we must do so in every situation. Knowing God’s heart through reading His Word and relying on “the wisdom that comes from heaven” (James 3:17) will help us know how to best respond in situations that might call for self-defense.” (source)

A person is privileged to threaten or intentionally use force against another for the purpose of preventing or terminating what the person reasonably believes to be an unlawful interference with his or her person by such other person. The actor may intentionally use only such force or threat thereof as the actor reasonably believes is necessary to prevent or terminate the interference. The actor may not intentionally use force which is intended or likely to cause death or great bodily harm unless the actor reasonably believes that such force is necessary to prevent imminent death or great bodily harm to himself or herself.

Interestingly enough it turns out on November 16, 2021, David French published an article entitled “Kyle Rittenhouse’s Acquittal Does Not Make Him a Hero“
