How that by revelation he made known unto me the mystery; (as I wrote afore in few words, Whereby, when ye read, ye may understand my knowledge in the mystery of Christ) Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit; That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the Gospel. (Ephesians 3:3-6)
There is a mystery that, without the Holy Spirit's help, the whole world can't understand. It's a truth that Paul knew, and God used the Apostle to the Gentiles to share this mystery with the rest of the world. What was the mystery that was revealed to Paul? It was Christ in you, the hope of glory. Paul knew that after we're saved, the focus is no longer about who we are but about Who is in us!
This was the message he was bringing to the world, and it's the same message that we bring to the world around us. Regardless of your background or your parentage, God has planned and purposed you to become a part of the family of God. In fact, Paul uses three words to depict what happened when we became a part of the family of God.
First, we are fellowheirs, which means the inheritance and blessings God has in heaven are given to those who become a part of the family on earth. Second, we are of the same body.
In other words, we are joined to the family of God. Third, we are partakers of the promise. All of the promises of God are ours; we only have to believe and receive them.
Practical Application – Meditate on the three promises that Paul described in Ephesians 3:6. When you are tempted to worry about not having enough, remind yourself that you are a "fellow heir." When you are tempted to worry about being lonely, remind yourself that you are joined to the family of God. When you are tempted to doubt God, remind yourself that you are a partaker of His promises.
