Lesson One gives a lot of information about Ephesus itself, and the greatest part is knowing God can establish a church in a place like that.
Again, chapters 1-3 are doctrinal, while 4-6 are practical. It seems that Paul is hoping to enlighten them, (1:18-19) that they would understand (comprehend) the benefits they had in Christ; then they could stand for God (Eph. 6:14) or in other words, walk worthy (4:1). Those first three chapters layout in detail a HUGE lading of benefits, prepared before the world began. Like benefits for those who work for a certain company, i.e. dental, healthcare, etc., God has predestined that everyone in Jesus Christ His Son, will have those benefits He has promised. They are so magnificent, incredible, awesome!, that we should walk WORTHY (4:1) of such a VOCATION.
Can you see that the walk is required because of the benefits of His calling, and not to OBTAIN the benefits? We’re saved by grace through faith, but true faith is demonstrated by our behavior (walk). 26 “For as the body without the spirit is dead, so faith without works is dead also.” (James Chapter 2)
Vocation, from the Latin vocare (verb, to call), is a term for an occupation to which a person is specially drawn, or for which they are suited, trained or qualified. Though now often used in secular contexts, the meanings of the term originated in Christianity. One definition mentions a person’s employment or main occupation. A VOCATION is different than a JOB, because it requires great dedication. In this case, it is US being worthy of the calling, not the calling worthy of us.
This vocation of God is to those in Christ
In Christ is a key phrase, and it’s “in Him” that all these spiritual blessings are found. Different than material things, spiritual blessings are many. That is, a spiritual blessing could be God’s approval, a prayer, a favor, God’s protection, so forth. But in the general sense, blessings are benefits.
Eph. 1:3 “Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ”
In Christ, there are spiritual benefits, and they’re all listed in Eph. 1-3. In the same way, the details of how we should behave in light of all those benefits, are detailed in Eph. 4-6.
‘Christ’, means “Anointed One”; the Chosen One of God (Eph. 1:4-6)
4 “According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: 5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, 6 To the praise of the glory of his grace, wherein he hath made us accepted in the beloved.”
The Olive Tree (Romans 11)
The grafting process
By being born again, even Gentiles (non-Jews) could be grafted in to the BENEFITS of God’s people, which we once “FOR JEWS ONLY!”
The blessings upon Abraham (Gal. 3:8)
Gen. 22 (15-18) – 15 And the angel of the LORD called unto Abraham out of heaven the second time, 16 And said, By myself have I sworn, saith the LORD, for because thou hast done this thing, and hast not withheld thy son, thine only son: 17 That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies; 18 And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.
Gal 3 (26-29)
26 For ye are all the children of God by faith in Christ Jesus. 27 For as many of you as have been baptized into Christ have put on Christ. 28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus. 29 And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise.
