Ephesians 3:2-5

2 Assuming that you have heard of the stewardship of God's grace (His unmerited favor) that was entrusted to me [to dispense to you] for your benefit,

  

3 [And] that the mystery (secret) was made known to me and I was allowed to comprehend it by direct revelation, as I already briefly wrote you.

  

Our Father is the only power that is able to reveal the Truth to us and it is only by our Father allowing us to comprehend His Truth that we will ever understand anything. Jesus prayed in John 17:1 that He be glorified by our Father, so in turn He could glorify our Father. We can only know the Truth because our Father gives us the Truth. So stop worrying about what you know and how you are used to serve the Kingdom. Our Father will give you what He wants to give you and when He wants to give it to you and it is all perfect and it is all in love. All things exist by our Father and through our Father and without Him nothing is possible, Colossians 1:16. Our Father knows what He needs for us to do. He knows when we are ready and able for Him to use us. Everything that He does is in love, He is love, so we will be used by Him when the time is perfect. 

Jesus is our Head, He is our Vine, and He is our Shepherd, so for us to be used to serve the Kingdom it must first come from Him. The branch isn’t expected to produce fruit on its own. The arm isn’t expected, nor can it, act on its own. An arm is part of a body that is controlled by a head and we are now members of Jesus’ body and Jesus is our Head. Jesus tells us in John 15:5 that without Him we can do nothing, but with Him we will be used to produce much and abundant fruit. We have entered into the rest of Jesus Christ, Hebrews 4:3. We have ceased from our own labors, Hebrews 4:10, and we now are the prisoners of Christ. Jesus leads us, He guides us, He strengthens us, and Jesus alone causes us to serve our Father. This is why there is now no condemnation to those of us who are in Christ Jesus, Romans 8:1. 

4 When you read this you can understand my insight into the mystery of Christ.

    

5 [This mystery] was never disclosed to human beings in past generations as it has now been revealed to His holy apostles (consecrated messengers) and prophets by the [Holy] Spirit.

What our Father is revealing to us has never been revealed before. All of us in Christ have received the Holy Spirit which means that all of us have received Jesus’ abilities and powers to understand everything. There are no mysteries to Jesus and we are one with Him. We have become one with all of His glory and honor, John 17:22, so there are now limits to what we can know and understand. Our Father can now use us perfectly just as He uses Jesus perfectly. Remember, we have been blessed with every spiritual blessing. The entire Kingdom of Heaven is ours. Our Father will hold nothing back from us. He will give us all exactly what we need, when we need it.
