Fear grieving God.

Mark 3:5 KJV

[5] And when he had looked round about on them with anger, being grieved for the hardness of their hearts, he saith unto the man, Stretch forth thine hand. And he stretched it out: and his hand was restored whole as the other.

Ephesians 4:30 KJV

[30] And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.

Grief is an intense emotion. Grief is what people suffer when their loved ones die. It is intense pain you can cause God.

“He’s God; He can handle it.” Is that true? God has a much bigger heart than people, so perhaps His pain is much greater.

If you care about God at all, you would avoid grieving Him, even if it cost you much.
