Peace is the tranquility of order in the midst of turmoil and chaos; it’s the very nature of Christ in us (Jn 14:27): an implicit, thankful trust in the eternal purposes of God, enabling us to walk in unspeakable joy in every circumstance. (1Pe 1:7-8) Christ is always at peace in Himself, and He offers Himself to us as peace; His yoke for us is easy, and His burden is light. (Mt 11:29)
Even so, peace seems elusive since our old nature resists the prescription, though it’s elegantly straightforward: Great peace have they which love thy law, and nothing shall offend them. (Ps 119:165)
The life of Christ in us loves Torah (Ro 7:22), and those who love Torah not only find peace, we find great peace.
The goal of Torah is to equip us for the godly life (1Ti 1:5), enabling us to understand that God has a plan, a purpose in all He allows, that His plan is good, and that He’s carrying out His plan according to His pleasure; nothing can stop Him. (Da 4:35)
In this knowledge, it’s impossible to be offended, to lose confidence in God, or to lose our hope in Him; with our eyes in eternal focus, nothing can happen to us or about us that will cause us to stumble in pursuing Him, or in seeking to please Him. (2Co 4:16-18) Torah defines moral reality; nothing else can, so being aligned with moral reality inoculates us against being offended, and maintains our internal order in the midst of conflict.
Peace isn’t the absence of conflict, it’s understanding that God’s in control in the midst of trouble, working out His glorious purpose. Peace is glorying in and rejoicing in His purpose, knowing He will glorify Himself in everything He allows. (Ro 5:3) The Father isn’t worried, anxious or afraid, and the Son is always doing what He sees the Father doing. Abiding in the Father and the Son (Jn 14:23), this is where we find life and peace. (Jn 17:3)
