Eph 1:19-20 And what is the exceeding greatness of his power to usward who believe, according to the working of his mighty power, 20 Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places
Let’s look at three very key words in verse 19 that give us a better understanding of what Paul said:
Mighty (ischus)—force, forcefulness, ability, power or strength.
Working (energeia)—efficiency, energy, strong, or effectual.
Power (kratos)—vigor, dominion, power, or strength.
Put these three words together in context and we have the full “potential power” that has been given to us as the bride of Christ. The source of that power is Jesus and He has given it to us in the Holy Spirit. We can operate in dominion over the enemy by the authority of Jesus, which is backed by the same power the Father used to raise Jesus from the dead, the Holy Spirit.
Rom 8:1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
He is the same Spirit that lives in us and quickens our mortal bodies. The appropriation of that power occurs through faith and belief in the One who placed it within us, Jesus.
One additional thought here. The ultimate power to save a lost soul is the power within us. The Holy Spirit is resident within us as the full embodiment of that potential power, ready to work the mighty miracle of salvation through us. All God wants is a willing and obedient heart that trusts in Him. With that He adds the power and we can see others literally “raised” from their spiritual death right in front of us by the Holy Spirit. Every time we share the Gospel under the direction of the Holy Spirit Jesus exercises dominion over the enemy.
No wonder all of heaven rejoices when someone becomes a believer in Jesus Christ (Luke 15:7, 10). We should also take great joy in those times when it results in the “dead being raised to eternal life.” Yes, it’s clear that the enemy doesn’t want us exercising our authority over him.
