27 Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid. John 14:27 (NIV)
Really, this is enough said. Receive the peace that passes understanding and simply do not let your hearts be troubled.
Notice, Jesus left His peace with you. Just pick it up and let it do its works. What is this IT? Nothing other than His Holy Spirit. The world gives peace by promising a trouble-less life. Christ promises peace by giving you His life, right now, in you…ready to get out of you.
Let Him meet each challenge and then let Him manage the same. If you do, you're in for a ride that ends, even in this life, in the lap of God.
