Two key biblical terms for the human reaction to a fresh glimpse of God: Magnify and Glorify

1. When We See More of God, We Say More of God

Key word: "Magnify" Lit. - to make great, or to consider and declare to be great

"And Mary said, My soul doth magnify the Lord, and my spirit hath rejoiced in God my Saviour" - Luke 1:46-47

"And there were seven sons of one Sceva, a Jew, and chief of the priests, which did so. And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye? And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded. And this was known to all the Jews and Greeks also dwelling at Ephesus; and fear fell on them all, and the name of the Lord Jesus was magnified." - Acts 19:14-17

It isn't that God is enlarged by our words, but rather that

When our view of God is enlarged, our praise magnifies the Lord

2. When God Reveals to Us a New Quality, We Bring the Quality to Light in Praise

Key Word: Glorify
Literally, To appear, to cause the dignity and worth of someone to be brought out into the open and acknowledged

When God Glorifies Himself:

"He shall glorify me: for he shall receive of mine, and shall shew it unto you" John 16:14

When We Glorify God with Our Lives:

"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven" - Matthew 5:16

When We Glorify God in Praise; We Bring His Invisible Qualities Out into the Open.

For example, His:

Mercy
"And that the Gentiles might glorify God for his mercy" - Romans 15:9

Power
"But that ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house. And he arose, and departed to his house. But when the multitudes saw it, they marvelled, and glorified God, which had given such power unto men." - Matthew 9:6-8

Holiness
"Who shall not fear thee, O Lord, and glorify thy name? for thou only art holy. . . " - Revelation 15:4
