Now after telling us what He has done in us, the Holy Spirit tells us it will be a battle to walk in this. All the powers of darkness will be against us. The battle, the decision, is to see if we will believe God or not. Some think all we need to do is quote verses. Quoting verses is a good place to start but this must be accompanied by works that show we believe what we are quoting.
Faith is an action word.
He knew them by their works. A storm of life comes to us and what is happening is in conflict with God's word. Be strong in the Lord, in the power of His might. Please note He said be strong in His might, not ours. That is faith in Jesus Christ.
