God lives in unapproachable light and cannot be seen. The Bible says our eyes are too pure to look upon evil. According to Hebrews, under the old law blood was required to cleanse and forgive sins, but Christ's unblemished blood cleanses our consciences through the Holy Spirit so we can serve the living God.

2. God… lives in unapproachable
light, whom no one has seen or can
see.
1 Tim 6:16

3.  Your eyes are too pure to look on evil;
you cannot tolerate wrongdoing.
Habakkuk 1:13

4. The law requires that nearly everything be
cleansed with blood, and without the
shedding of blood there is no forgiveness.
Hebrews 9:22

7.  How much more, then, will the blood of
Christ, who through the eternal Spirit offered
himself unblemished to God, cleanse our
consciences from acts that lead to death, so
that we may serve the living God!
Heb 9:14
