The Spirit is the guarantee [the first installment, the pledge, a foretaste] of our inheritance until the redemption of God’s own [purchased] possession [His believers], to the praise of His glory.

don't cease to give thanks for you, making mention of you in my prayers,

in which he wrought in the Christ in raising him from among the dead, and he set him down at his right hand in the heavenlies,

and has raised us up together, and has made us sit down together in the heavenlies in Christ Jesus,

For it is by His unmerited favor through faith that you have been saved; it is not by anything that you have done, it is the gift of God.

not the outcome of what you have done ??lest anyone should pride himself on that;

Wherefore remember that ye, once nations in the flesh, who are called uncircumcision by that called circumcision in the flesh done with the hand;

For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us;

Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace;

This was done so that now God's many-sided wisdom could be made known through the church, to the rulers and authorities in the heavenly realms [Note: "Heavenly realms" here refers to the world around us, where these angelic beings (good or bad) view the unfolding of God's wonderful plan],

For this cause I go down on my knees before the Father,

so that Christ may dwell in your hearts through your faith. And may you, having been [deeply] rooted and [securely] grounded in love,

and that, he went up, what is it except that he also went down first to the lower parts of the earth?

he who went down is the same also who went up far above all the heavens, that He may fill all things --

[This is to be done] until we all [eventually] arrive at unity of the faith and full knowledge of the Son of God; at complete [spiritual] maturity; at the [full] height of Christ's [spiritual] stature.

So we shall no longer be children, tossed up and down, and blown about by every wind of teaching, tricked by the craft of men in the snares of misleading error;

Therefore, rejecting all falsehood [whether lying, defrauding, telling half-truths, spreading rumors, any such as these], speak truth each one with his neighbor, for we are all parts of one another [and we are all parts of the body of Christ].

Be ye angry, and sin not: let not the sun go down upon your wrath:

and don’t give the Devil an opportunity.

And don’t grieve God’s Holy Spirit. You were sealed by Him for the day of redemption.

Do not let any one deceive you with specious arguments. Those are the sins that bring down the Wrath of God upon the disobedient.

Therefore don't be partakers with them.

Don’t participate in the fruitless works of darkness, but instead expose them.

For it is a shame even to speak of those things which are done of them in secret.

For this reason He says,

“Awake, sleeper,
And arise from the dead,
And Christ will shine [as dawn] upon you and give you light.”

So don’t be foolish, but understand what the Lord’s will is.

And don’t get drunk with wine, which leads to reckless actions, but be filled by the Spirit:

You husband, love your spouse, even as Christ loved the church, and laid down his life for her:

Fathers, don’t stir up anger in your children, but bring them up in the training and instruction of the Lord.

Don’t work only while being watched, in order to please men, but as slaves of Christ, do God’s will from your heart.

because you know that everyone will receive a reward from the Lord for whatever good he has done, whether he is a slave or free.

Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
