About the face...

But if the ministry of death, in letters engraved on stones, came with glory, so that the sons of Israel could not look intently at the face of Moses because of the glory of his face, fading as it was, how will the ministry of the Spirit fail to be even more with glory? (2 Corinthians 3:7)

And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit. (2 Corinthians 3:18)

For God, who said, “Let light shine out of darkness,” has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ. (2 Corinthians 4:6)

There is another kind of face:

Therefore the showers have been withheld, and the spring rain has not come; yet you have the forehead of a whore; you refuse to be ashamed. (Jeremiah 3:3).

and thou hadst a whore's forehead; was impudent and unconcerned, repented not of sin, or blushed for it, though such judgments were upon them; ~Gill's Exposition

We gain a bit of context here about the Jeremiah verse, from Ligonier devotional-

This analogy lies behind today's passage wherein Jeremiah accuses the old covenant community of having "the forehead of a whore" and refusing "to be ashamed" (3:1–3). A harlot can only "work" consistently if she suppresses the shameful feelings that attend her deeds. She must lose all sense of embarrassment and be unable to blush. Israel has a harlot’s forehead, she no longer turns red with shame over her wickedness (6:15). ~Ligonier

So there's two kinds of faces. The one that glows as it basks in the light and glory of Jesus, and the face that turns away to seek sin, and is so taken by it that it refuses to blush.

John Owen wrote about Indwelling Sin in the Believer, and here in chapter 8 in modernized language he discusses the deceitfulness of sin,

It is always carried on by degrees, little by little, so that the whole design and aim is not revealed at once. ... Now, this effect of the deceit of sin is worked upon the mind. The mind or understanding, as we have shown, is the guiding, the conducting faculty of the soul. It goes before — in discerning, judging, and determining — to make the way of moral actions fair and smooth to the will and the affections. 

For our faces to glow, as it were, our face must be looking at Jesus, our mind consumed with Him, stirring our affections, convicting us of sin, transforming it to His mind.

When we look away, the deceitfulness of sin will draw us away as James 1:14 KJV says

But every man is tempted, when he is drawn away of his own lust, and enticed.

You see the order of things. The temptation comes after he is drawn away. We are drawn away when we look away.

The solution: don't look away.

Be vigorous in prayer life, stay reading the Word, assemble with the saints regularly, fellowship with believers to whom one can be transparent and accountable, and frequently enough so they will know you.

You have said, "Seek my face." My heart says to you, "Your face, LORD, do I seek." (Psalm 27:8)
