It's very easy to hear and be convinced by negative thoughts and emotions. If you are convinced by negative emotions enough times, you begin to (firmly) believe them, a they can form a sort of foundation underneath you. This can become the foundation that you walk daily with, and wake up with each morning; it can be the driver of your decisions, attitudes, and the very things you desire. 

But this sort of foundation is ultimately not true. Doubt, pessimism, and disapproval of oneself run contrary to our original creation. God did not create anything that is not good. Furthermore, we cannot find true joy, peace, or validation apart from God. So negative thoughts are actually lies. 

"Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy—meditate on these things." (Philippians 4:8)

Then God said, “Let Us make man in Our image, according to Our likeness; let them have dominion over the fish of the sea, over the birds of the air, and over the cattle, over all the earth and over every creeping thing that creeps on the earth." So God created man in His own image; in the image of God He created him; male and female He created them. (Genesis 1:26-27)

We see in these verses a collective human responsibility to (1) meditate on good things, and (2) be responsible for the dominion and stewardship over God's creation. As well as a deeper responsibility we have to remember that all negative thinking (logismoi) are lies that aim to turn us away from God. 

So if our only focus is to steward our minds and the little patch of life we find ourselves in, we have done a great service to God and towards our own purpose. But this can be very difficult when we are constantly targeted by negative thought patterns flying past us. 

Think about thought patterns, emotions, and every thought that flies past your mind as the weather. The wind is always traveling past you; every thought begins as a gentle wind. But to begin allowing thoughts to sway you, as a tree sways in the wind, can eventually threaten the roots of the tree. A tree that is not rooted in "true, noble, just, pure, good, virtuous and praiseworthy things" will be uprooted and taken up by the winds of stormy thought patterns. 

The person that observes and then ignores negative thinking in favor of remembering God can find stillness and good ground for the planting of proper roots of beautiful thoughts in their heart. Gratitude, joy, honesty, and prayer help us in this.

Hey, thanks for reading! I know I may have rambled on a bit; this is a topic I want to keep coming back to because of how much it matters to all of us. It's easy to feel alone in this struggle, but God is constantly pursuing us. Turn to Him.
