Armour

Ephesians 6:11-12 says, Put on all the armour that God gives, so you can defend yourself against the devil's tricks. We are not fighting against humans. We are fighting against forces and authorities and against rulers of darkness and powers in the spiritual world. 

Whether you like it or not, if you are a Christian, you are in a spiritual battle. The Enduring Word Bible Commentary says, You are in a spiritual battle. If you are ignorant or ignore that fact, you probably aren’t winning the battle. The forces, authorities, rulers of darkness and powers refer to Satan, his army and the darkness of sin. Here's what the Bible says about these dark forces:

Jesus is above these dark forces - Ephesians 1:19-21
I want you to know about the great and mighty power that God has for us followers. It is the same wonderful power he used when he raised Christ from death and let him sit at his right side in heaven. There Christ rules over all forces, authorities, powers, and rulers. He rules over all beings in this world and will rule in the future world as well.

They can't separate us from the love of Jesus - Romans 8:38
I am sure that nothing can separate us from God's love—not life or death, not angels or spirits, not the present or the future.

Jesus defeated these powers at the cross - Colossians 2:15
There Christ defeated all powers and forces.

Jesus will destroy these powers - 1 Corinthians 15:24
Then after Christ has destroyed all powers and forces, the end will come, and he will give the kingdom to God the Father.

We don't have to fear these powers of darkness, but to win the battle we have to acknowledge it exists and put on the full armour of God. More on that in the next study.
