I had the gift of leading a devotional among the team in the past week as part of our team meeting.
We read Philippians 4:4-8. If you haven't read it lately, read it. Through the stresses of the day, the difficulties we face, our challenges, our distractions and our emotions. The words ‘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 heart and your mind in Christ Jesus' are truly wonderful words. If I genuinely reflect on the times I have prayed for God's work in my life I can see a peace that I would not ever have otherwise. If you reflect on it too, I believe that you will find the same thing.
I also have a default position, which is using God as a Lucky charm (only praying when I ‘need’ or strongly desire something). I’m sure God knows that is my normal heart, so every time I read it I feel like God had me in mind. God knows what we need, of that I am certain. But not only that, he gives us the assurance that only He is able to; that the master of the universe has our concerns in mind and through Him we will have a peace that we can’t understand, but can be ever-so grateful for.
