I had to write a memoir for the first time. A whole page, anything I wanted, something I would look back on and think, "That was so me back then...". I wrote random thoughts that were in my head. Looking back, it was totally me.
We work so hard to be someone we aren't, and sometimes we cover ourself with so many lies, we don't know who we are really underneath. A little burst of random thought, uncensored by the barrier of lies, onto a piece of paper, something readable, keeps you sane.
Try it now. See what your real self is like.
It is also useful in your core beliefs too. Write down what you feel about God. Sometimes our mind is filled with doubts or worries about what we believe in. They crowd around us, hemming us into a corner, not letting us talk back.
I wrote, God is good! He has forgiven me! He loves me! He cares for me! It pulled me back to the reality of the amazingness of God's love. I feel like shouting for joy! Go God! I don't have to make it sound good, he knows what I mean.
Doing this is a good foothold in the midst of a sinking faith. Remember what God has done for you, and try and get that through your barrier of lies. Hopefully, that might free you from your chains.
