I am going to break down and interpret each line of scripture that Paul talks about, because they are powerful words. The following is what Paul said:
10 Finally, be strong in the Lord and in his mighty power.
The Lord will give us what we need (the strength, power and boldness) to move on with our goals.
11 Put on the full armor of God, so that you can take your stand against the devil’s schemes.
Trust in God and stay atuned to Him. That way we will be able to stand boldly against any plot against us.
12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. When people and things come against us, it's not them we need to fight, but that spirit that lives in them. There are many forces working against us, in the form of people, places, and things.
13 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. The amour of God is strong. Nothing can come against it. All will be defeated. So as we continue in our faith (trust in Him), then when it's all said and done, we will come out victorious.
14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place15 and with your feet fitted with the readiness that comes from the gospel of peace.
Once we are fully equipped, then carry on. We will have nothing to worry about. Just do our part and the Lord will continue to fight for us.
16 In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one.
Simply put, remain steadfast in our belief that God will do it. He will protect us against all the evil forces coming our way. He will stop them in their tracks if they even get that far.
17 Take the helmet of salvation and the sword of the Spirit, which is the word of God.
Salvation and rebirth in Christ is the beginning of hearing from God. Our life will change and continue to change as we grow in Him. We will be even more awesome, because of it.
18 And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people.
Pray in tongues, a spiritual language of communication with the Lord, and pray without ceasing.
19 Pray also for me, that whenever I speak, words may be given me so that I will fearlessly make known the mystery of the gospel, 20 for which I am an ambassador in chains. Pray that I may declare it fearlessly, as I should.
Like Paul, please continue to pray that I will write and speak for the Lord. I pray that you will do the same in whatever it is He placed inside of you. Iron sharpens iron.
In order to be strong, mighty and influential, we need the Armor of God. Nothing worthwhile will happen without it.
