Trinity

One of the most surprising things about God is how He displays emotion. Perhaps this is biblically correct if we regard Him as a person, but it is still amazing that a person who knows and sees all can experience feelings. Can we use the word experience with regards to God? Can we say that He reacts to things, when He knew before time that they would occur?

Along with loving us, God displays anger, jealousy, sadness.

-Do not worship any other god, for the LORD, whose name is Jealous, is a jealous God. Exodus 34:14

-The LORD's anger burned against Israel and he made them wander in the desert forty years, until the whole generation of those who had done evil in his sight was gone. Numbers 32:13

-Do I take any pleasure in the death of the wicked? declares the Sovereign LORD. Rather, am I not pleased when they turn from their ways and live? Ezekiel 18:23

It is easier to imagine Christ having emotions, since He took on flesh. One of the first examples that comes to mind is His wrath toward the money changers at the temple.

-Jesus entered the temple area and drove out all who were buying and selling there. He overturned the tables of the money changers and the benches of those selling doves. Matthew 21:12

And He displayed compassion.

-A man with leprosy came to him and begged him on his knees, "If you are willing, you can make me clean." Filled with compassion, Jesus reached out his hand and touched the man. "I am willing," he said. "Be clean!"  Immediately the leprosy left him and he was cured. Mark 1:40-42

Maybe it's easier to picture God as a loving Father and Christ as a humble Teacher (both with beards, of course), but what about the Holy Spirit?

I've always had a harder time "picturing" the Holy Spirit. I can feel His presence, but what is He like as a person?

The Holy Spirit is linked with personal emotions as well.

-And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption. Ephesians 4:30

There you have it. One of the mysteries of our faith.
