Holly

“whom God displayed publicly as a propitiation in His blood through faith. This was to demonstrate His righteousness, because in the forbearance of God He passed over the sins previously committed; for the demonstration, I say, of His righteousness at the present time, so that He would be just and the justifier of the one who has faith in Jesus.” (Rom. 3:25-26 ESV)

The reason for the season reminders all around us 

Christmas decorations and their symbolism can remind us of the true reason for the season, which is Jesus. This is especially true of holly, its structure, its berries, and its colors—the evergreen quality of the holly tree is metaphoric for eternal life. Holly's sharp leaves are said to symbolize the crown of thorns worn by Christ, while the berries represent his blood.

Therefore

When we see holly during the holiday season, it should remind us of Jesus, His mission, and the eternal life He provided for us.

“For I have come down from heaven, not to do My own will, but the will of Him who sent Me. This is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. For this is the will of My Father, that everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day.” (John 6:e8-40)
