I have found it very difficult to “Be still, and know that I am God.” On so many occasions, as I have tried to give my full attention to the power, sovereignty, and love of our Savior, 1000 small worries and trivial issues rush into my mind and draw my attention away from him. So many people have come to me with the same complaint that I believe it is a common experience for all of us.
My answer for them has been, like anything else we do, especially a discipline we are trying to instill, the more you do it, the better you get at it. It gets easier and more effective with practice and time. So, keep after it. Please don’t let the distraction dilemma discourage you from seeking that personal encounter with Jesus.
I came across an article recently that I think will also help. It’s titled, Shape Your Worries into Prayers (https://thedisciplemaker.org/shape-your-worries-into-prayers). It has some good ideas about what to do with those worries and trivialities when they rush into your mind. I hope it helps you enter into the rest that Jesus wants you to enjoy.
