How we think and what we meditate on determines how we feel and thus how we act. So when we feel insecure, unstable, restless and anxious, we are likely mediating on the things of the world. When we fix our mind on who God is, then we will begin to change how we feel and the overflow of a heart set on the Lord is a life of fruit bearing.
Get these 10 life-giving verses on the attributes of God to print out and cut out. I have them taped on my mirror, tucked in my phone case, propped up by the sink, anywhere I spend mindless time. In those moments I can fix my mind on truth rather than let my mind wander to the things of the world.
