The truth is, God will strengthen me when I come to the end of myself. He will increase my capacity for exertion and increase my power and endurance. This is because of the greatness of His love, grace, and mercy, and not because I merited His strength by works. This is the truth that the Bible teaches – He has not left me on my own to deal with the difficulties of life. Thoughts and feelings of powerlessness are lies which the enemy lies to us. We do not have to accept those lies. We can reject the lies and believe the truth instead.
This is how I trained my heart and mind to receive and believe the truth:
“I am feeling __weak__, but it is only a feeling brought on by my past. It is not a true reflection of my current reality. My reality is determined by the word of God, and this is what it says: __repeat Scripture__.”
The word of God is powerful, living and active, the weapon of our warfare which is effective against all the lies of the enemy and mighty to tear down strongholds (2 Cor 10:4).
