These are your question:

But about that plan, which you said HE provided for us to see Him, can you tell us how? Can you cite verses?

Because I have read in one verse saying;

1 Timothy 6:16 Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.

It says, ‘dwelling in the light which NO MAN CAN APPROACH INTO, WHOM NO MAN HAD SEEN, NOR CAN SEE’. So how can we see Him then?

HAD SEEN being PAST TENSE. NOR CAN SEE being, i think PRESENT PROGRESSIVE. Correct me if I am wrong with that. So how will you resolve this, then?

Jet, this is my answer to your question above:

God has a plan just read again two verses up and continue to 16:

14That thou keep this commandment without spot, unrebukable, until the appearing of our Lord Jesus Christ:

15Which in his times he shall shew, who is the blessed and only Potentate, the King of kings, and Lord of lords;

16Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.

I believe, that the Church of God, those who follows all the commandments and prophecies given especially to them, will see God.

1 Corinthians 1
1Paul, called to be an apostle of Christ Jesus by the will of God, and our brother Sosthenes,

2To the church of God in Corinth, to those sanctified in Christ Jesus and called to be holy, together with all those everywhere who call on the name of our Lord Jesus Christ—their Lord and ours:

3Grace and peace to you from God our Father and the Lord Jesus Christ.

4I always thank God for you because of his grace given you in Christ Jesus. 5For in him you have been enriched in every way—in all your speaking and in all your knowledge—

6because our testimony about Christ was confirmed in you.

7Therefore you do not lack any spiritual gift as you eagerly wait for our Lord Jesus Christ to be revealed. 8He will keep you strong to the end, so that you will be blameless on the day of our Lord Jesus Christ. 9God, who has called you into fellowship with his Son Jesus Christ our Lord, is faithful.

1 John 3
1Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not.

2Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.

3And every man that hath this hope in him purifieth himself, even as he is pure.

With these things I learned, I still remain an unworthy servant.

Job 12:9-10

Do you believe that angels are spirits? Yes, indeed, they are spirits. God made them.

And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire.
Hebrews 1:7

Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?
Hebrews 1:14

Regarding to your question, God made them.
