Jesus is the reason for the season of Christmas celebration...but how about we take it further than just one day!
1 Corinthians 15:2-7 Amp. Says this:
2 By this faith you are saved [reborn from above—spiritually transformed, renewed, and set apart for His purpose], if you hold firmly to the word which I preached to you, unless you believed in vain [just superficially and without complete commitment].
3 For I passed on to you as of first importance what I also received, that Christ died for our sins according to [that which] the Scriptures [foretold], 4 and that He was buried, and that He was [bodily] raised on the third day according to [that which] the Scriptures [foretold], 5 and that He appeared to Cephas (Peter), then to the [a]Twelve. 6 After that He appeared to more than five hundred brothers and sisters at one time, the majority of whom are still alive, but some have fallen asleep [in death]. 7 Then He was seen by James, then by all the apostles, 

Let's remember the Lord's sacrifice and celebrate salvation through his blood sacrifice that paid our sin price on the daily. Kissing the Son in love and honor so He have no cause against us!

Live a life of celebrating Christ on Christmas and beyond each day! Amen and Amen!
