Rejoice in the Lord always. I will say it again: Rejoice! Let your gentleness be evident to all. The Lord is near. Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things. Whatever you have learned or received or heard from me, or seen in me—put it into practice. And the God of peace will be with you.
If you take this passage seriously, then you have to acknowledge that it’s not easy to receive God’s peace. Certainly in answer to the prayers of others, we might find ourselves experiencing it. But from this passage it comes through believing prayer, reflection on what is good and true, and imitation of Christ, and specifically those who follow him. Far from automatic, or from being easy, for that matter.
God’s peace experienced is a sense of well being with the assurance that no matter what, somehow all will be well. At least a sure confidence in God through it all.
I love the experience, but I don’t see knowing in Scripture primarily in terms of experience. The feelings come and go, but faith remains the same. Faith by nature means trust and trust involves a dependence which means “hands off.” And yet there is our part, as we see in the above passage.
I often find in a given matter, it’s not without at least some struggle and prayer and time before I get a sense of peace one way or another. God is faithful and God wants us to find his peace always, through it all. By faith in and through Jesus.
