Seeing God seems to be concomitant with being holy and doing good.
3 Jn 1:11
11††††† Dear friend, do not imitate what is evil but what is good. Anyone who does what is good is from God. Anyone who does what is evil has not seen God.† (NIV)
For God, who said, "Let light shine out of darkness,"[ 4:6 Gen. 1:3] made his light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ.
(Whole Chapter: 2 Corinthians 4 In context: 2 Corinthians 4:5-7)
This passage shows that the face of Christ was seen by many before and after his resurrection, and can still be experienced.† However:
18††††† No one has ever seen God, but God the One and Only, who is at the Father's side, has made him known.† (NIV)
Who is both God and ďat the fatherís sideĒ?†
32God has raised this Jesus to life, and we are all witnesses of the fact. 33Exalted to the right hand of God, he has received from the Father the promised Holy Spirit and has poured out what you now see and hear.
I Jn 4:12
12††††† No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us.† (NIV)
So then, no one has other seen God the Father, but many have seen Jesus Christ, who is God.† These and other epiphanies must be Jesus Christ.†
21††††† When the angel of the LORD did not show himself again to Manoah and his wife, Manoah realized that it was the angel of the LORD.
22††††† "We are doomed to die!" he said to his wife. "We have seen God!"
23††††† But his wife answered, "If the LORD had meant to kill us, he would not have accepted a burnt offering and grain offering from our hands, nor shown us all these things or now told us this."
24††††† The woman gave birth to a boy and named him Samson. He grew and the LORD blessed him,† (NIV)
30 So Jacob called the place Peniel, saying, "It is because I saw God face to face, and yet my life was spared."† (NIV)
2 Chr 7:14
14††††† if my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land.
7††††††† Hear my voice when I call, O LORD; be merciful to me and answer me.
8††††††† My heart says of you, "Seek his face!" Your face, LORD, I will seek.
9††††††† Do not hide your face from me, do not turn your servant away in anger; you have been my helper. Do not reject me or forsake me, O God my Savior.
10††††† Though my father and mother forsake me, the LORD will receive me.† (NIV)
4††††††† Look to the LORD and his strength; seek his face always.† (NIV)
