"In the exercise of His will He brought us forth by the word of truth, so that we might be, as it were, the first fruits of His creatures." James 1:18
"if you will not believe, you surely shall not last." Isaiah 7:9b
"refuse evil and choose good." Isaiah 7:15b
Your words, your choices create life or death in your life and in the lives of those in your world. You have that much power in you.
"make straight paths for your feet, so that the limb which is lame maybe not be put out of joint, but rather be healed."
Even if you are feeling doubt and fear, you can choose to believe, choose to repeat that God promise to yourself. By doing this you are giving yourself the straight path rather than a crooked one. You were created to live a spiritual life not a fleshly carnal life.
"For the mind set on the flesh (which is eyes on yourself and others, feelings of doubt and fear, etc) is death, but the mind set on the Spirit is life and peace" Romans 8:6
I know I've written about this before but I'm writing about it again because we need constant reminding, especially if we are having a rough time. Choose. Use your words to bring life, to speak life into your life and others. Speak life -- you were made in the Image of the Creator. You too can create from your words.
