Jesus is our peace.
How to focus on Him when all else is tumultuous?
Focus on His word. His word is life and can still all the loud, obnoxious voices.
Read it, pray it, meditate on it, sing it. Keep it always in your heart.
When I was first a Christian, I was still vexed by much darkness as I had been involved with new age and other darkness. I learned very quickly if I read the Holy Bible out loud, or even to myself, I seemed to be at peace. It made no difference where I read, anywhere was powerful. Jesus calmed the storms.
As our world gets more filled with dark things that are not of God, things that are from men or other areas, such as the occult, the waves of deception, keeping His word on our minds will help us stay focused on the good and the beneficial things.
Memorize His word. Memorize individual scriptures and whole chapters and psalms. Find a way to hide His word in your heart. This has to be a priority. We have access to the Holy Bible now while it is day. The night is coming when no man can work. but there is no guarantee we always will have God’s Word as readily available as it is now. Some would even like the Bible to be considered hate speech.
Even now, we cannot read the bible whenever we want. We need to know some of it by heart so that in those moments when we need to hear God’s word, it is easily accessible to us.
