As we get closer and closer to the day in which we celebrate the birth of Jesus, take a minute to remember what you have been given. When Jesus saved us He gave us peace with God.
Peace with God vs. the Peace of God
Peace with God is an objective peace. It doesn't come from within ourselves. It is a gift from God. A gift given to us by Jesus. Jesus paid the penalty for our sins on the cross and, when we repent and trust in Him, He is faithful to forgive our sins and save us. Jesus absorbed the wrath of God that should have been ours, and in exchange He gives us peace with God. This peace is a fact, not a feeling. It is finished and it never changes or diminishes.
"Therefore being justified by faith, we have peace with God through our Lord Jesus Christ." (Romans 5:1)
Peace of God is a subjective peace. We have it when we experience the peace that trusting Jesus brings. It is not simply a fact, it is also a feeling. We know that Jesus has given us the Holy Spirit and that His grace is sufficient in all things, so when we keep our eyes on Him and we rightly remember Who He is, what He has done for us and who we are in Him, we will experience the calm of being in Him. That is experiencing the peace of God. However when we allow anxiety and fear to set in, our peace dwindles and our joy is diminished.
Paul warns us against such worry and tells that it is "with thanksgiving" that we are to come to God. We are to be remember all that God has given us and give Him thanks. Then we will find our rest in Him and we will experience the peace of God.
