Forgiveness is the root of peace. You will never find peace without forgiveness.
Whether you are struggling with unforgiven sins from your past or you are holding on to the sins of others upon you, take a minute to let God help with letting go so you can find the peace that can't be found otherwise.
I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world.
