When the Word says a peace is available that is beyond your current ability to understand it does not mean this peace is something you are not able to experience. The offer of God's peace is not put out in front of you as something unattainable that continues to run ahead of your life out of reach as a spiritual tease. This is a supernatural peace that is always available for those who will go after it and take hold of its blessing.
When Paul wrote about peace, he spoke about a peace that was the result of a process. This peace was offered to anxious people who had let fear invade their thinking. Paul said, “Be anxious for nothing…” No matter how valid the reasons for your anxiety appear to be anxiety is a liar who needs to be challenged. Instead of allowing anxiety rule and reign in your thinking make an exchange with God. Paul said to give God your anxiety through prayers of thanksgiving, “Then you will experience God's peace, which exceeds anything we can understand.” The word, “Then”, is so powerful because it reveals the hinge point in the process of attaining peace. Do the exchange – then – the peace will come, not before.
If you continue to hold on to fear and justify its existence it will continue to lead your response to life instead of being led by the Spirit of God. This is not beyond your ability to do. God will never ask you to do something that your faith cannot engage and partner with, no matter how weak this season of anxiety has made you. This is why the act of worshipping, praying and thanking God, when nothing makes sense, will become the invitation for this peace to come and invade your thinking displacing the unsettled nature of your current reality.
