In Ephesians 1:19-20 Paul is talking about the power of Christianity. It’s more than the power of the resurrection. It’s the power of Christ’s ascension and enthronement. This same power is also at work in the lives of Christians.
Is there a power in your life that is somehow a reflection of the power that raised Jesus Christ from the dead? Don’t be satisfied with powerless Christianity because Christianity is all about a God who acts. Christianity is a matter of power and of God, it always has been and always will be. Unless God shows up, it’s either dead religion or dead paganism. Show me a genuine Christian and I will show you something that God is responsible for. To bring one soul to repentance and faith requires the almighty power of God.
