The following article is extracted from brother Harold St. John's article with the same title, the article is longer in the original, just including the main part, hope it helps :)
"Let us imagine that we are to begin on January 1st, and that we propose to devote the whole month to the Ephesian letter, giving twenty minutes each morning after our prayer season or before it, as we prefer, (George Muller advocated Bible reading first and then prayer, but he was not thinking of study, but devotional reading).
On January 1st we quietly read our book through without stopping, using the Authorized Version.
On January 2nd, we again read it, but now from our Revised or other translation, this time noting important variations that may strike us. The references to these may be jotted down on a separate slip of paper for verification later.
On January 3rd we re-read, this time noting the paragraph or main divisions into which the Epistle falls. (Make your own paragraphs and then see if the RV agrees with you). At the same time jot down the principal topics and dominant ideas which run through the book.
You will undoubtedly have been struck by the occurrences of the phrase "heavenly places", found nowhere else in Scripture, and on the fourth morning would trace this phrase as your "morning meal", and would find the following five passages:
1:3 We are blessed with Christ in the heavenlies.
1:20 Christ has gone up and is enthroned there.
2:6 We too are seated in Him in the same place.
3:10 Heavenly beings there must learn in us the "many coloured wisdom of God."
6:12 There we meet Satan face to face in our hidden prayer life and on that battlefield we win our victories.
Imagine going out to business with your heart overflowing with such thoughts as these. You meet a downcast brother on the train or at lunch and you tell him your morning's find, and going over it will bless you and will restore to him the joy of salvation. Always try and hand on what you get, and meditate on it in spare moments. This is "eating the book" (Ezek 2:8; Jer 15:16).
The following day (January 5th) we take the thought of "walking" (incidentally noticing the various attitudes referred to in the epistle, chap. 2 and chap 3, kneeling; chap 4, walking; chap 6, standing). We find the verb eight times and divide it up thus:
a. How not to walk (2:2; 4:17), three ways.
b. How to walk (2:10; 4:1; 5:2,8,15), five ways.
Then on January 6th, we take the allusions to love - first as a noun ten times see (1.4, 15; 2.4; 3.18,19;4.2,15,16;5.2; 6.23).
Then as a verb ten times, and "beloved" twice (6.1,21) (1.6 is a verbal form).
It would not be a difficult thing to love your fellows as you went about that day!
On the 7th you would consider the question of measurements throughout the book. First in chap. 4 the three things measured, the gift of Christ, the stature of Christ, the increase of the body (5.2,13,16).
Then the four dimensions of 3.18 would be looked at and the height and depth of Christ's ascent and His descent in 4.8-12; and finally, the twenty one places where "according to" (Gr. kata) erects a standard for the mind, for instance, 1.5,7,9,etc. This can only be done fully with the Englishman's Concordance(The Word study Concordance also can, but its only for Greek and not Hebrew :) ) or by those knowing Greek (and also "in Him")
The day following you would consider the expression "In Christ" occurring ten times, noticing that the phrase is always found in chap. 1-3. This would remind you of the structure of the epistle, viz. 1-3 - the Christian's calling (in Christ). 4 to 6.9 - The Christian's conduct (in the world). 6.10-24 - The Christian's conflict (in prayer).
Finally, you will want to trace the early history of the Ephesian church and turning to Acts 19 you will be amazed at the skill with which Luke, the supreme literary artist of the NT, has chosen to record just those incidents which illuminate the subjects of the Epistle, for instance:
Luke tells how the original members of the Church were twelve disciples who had not even heard of the Holy Spirit. How instructive in the light of such a beginning to notice the full and varied teaching, in this Epistle, as to the operations and offices of the Spirit (perhaps 12 passages) in contrast with the sister Colossian letter, in which He, probably, is not once named.
Then Luke records the incident of the seven sons of a Jewish chief of the priests who sought to expel evil spirits but were put to shame. In the light of this, see the warning of 6.12; just as the would-be exorcists fled away naked and wounded, so shall we unless we learn how to stand our ground, fully clad with the panoply of God.
Lastly, the memory of the riot in Diana's Temple may have suggested the analogy of that radiant shrine which "groweth unto an Holy Temple in the Lord" (chap 2.21).
Your next task will be to divide the book into about ten sections, one of which will be studied carefully each day, especially noting the thread of the writer's thoughts. As you will be fairly familiar with the text by this time, it would be quite and easy task to commit the daily section to memory. A friend of mine memorized the whole of Paul's epistles during his morning walk to business.
Finally, you will undertake the pleasantest and most valuable part of your study, and will devote the last week of the month to revision and to permanently recording the results of your work. You will take each day's rough slip, check your finding with the Concordance and then as neatly as possible enter in the fair copy book the references and the spiritual lessons gathered.
For instance, names and titles of Christ in the Epistle:
1. Head of church (1.22,5.23)
2."Our peace" (2.14)
3. Chief corner stone (2.20,etc)
When your month's labour of love is finished and you look at your spoils, what will be your gain?
First, you have acquired a working foundation knowledge of one book of the Bible. The work done once in this way need never be repeated, and you can refresh your memory at any time with a glance at the note book.
Secondly, you will have begun one of those habits by which we discipline ourselves into godliness and make high and holy things almost instinctive.
Lastly, you will have climbed the highest altitude and breathed the purest air in all the New Testament.
I may add that "two are better than one," and that there is no more solid cement on which to base wedded happiness than on Bible study in harness."
May our study of the Word indeed be joyful and our hearts humble remembering continually all that we have learned and gained is from the light that He has given us in the first place, and with whatever that is learned be put in practice, and with all the beholding of our Lord may the becoming like Him increase in like measure, may Gal 2.20 truly be understood and lived out moment by moment until He calls us home.
Shalom.
:)
