Why is it so important to establish in our hearts that neither God nor His word ever changes? We probably have all experienced people who continually change their mind or can’t make up their mind. It can be very frustrating not knowing how a person might react from moment to moment. Have you ever gone into work and wondered what kind of mood your boss will be in that day? Have people ever had to wonder that about you? The reason people can be “unstable” in their ways is they are allowing themselves to focus on things that can fluctuate such as the stock market or the price of gas or even other people. In other words, they focus on the world around them. If you allow yourself to be pulled back and forth between what God offers and what the world offers, you are double-minded. And we know that a double-minded person is an unstable person. But when a person is able to see past these worldly things and focus on a God in whom there is no variation or shadow of turning, this produces a rock-solid confidence that cannot be shaken! There is only one place you will find complete stability and that is in Jesus!

6 But when you ask him, be sure that your faith is in God alone. Do not waver, for a person with divided loyalty is as unsettled as a wave of the sea that is blown and tossed by the wind. 7 Such people should not expect to receive anything from the Lord. 8 Their loyalty is divided between God and the world, and they are unstable in everything they do. James 1:6-8 (NLT)  

17 Every good gift and every perfect gift is from above, coming down from the Father of lights, with whom can be no variation, neither shadow that is cast by turning. James 1:17 (ASV)  

24 “These words I speak to you are not incidental additions to your life, homeowner improvements to your standard of living. They are foundational words, words to build a life on. If you work these words into your life, you are like a smart carpenter who built his house on solid rock. 25 Rain poured down, the river flooded, a tornado hit—but nothing moved that house. It was fixed to the rock. Matthew 7:24-25 (MSG)
