Luke 2:7
And she brought forth her firstborn son, and wrapped him in swaddling clothes, and laid him in a manger; because there was no room for them in the inn.
The twenty-fifth of December is supposed to be the day of the birth of Jesus Christ, and its observance has become customary and popular. But yet there is no certainty that we are keeping the veritable day of our Saviour’s birth. History gives us no certain assurance of this. The Bible does not give us the precise time. Had the Lord deemed this knowledge essential to our salvation, He would have spoken through His prophets and apostles, that we might know all about the matter. But the silence of the Scriptures upon this point evidences to us that it is hidden from us for the wisest purposes.
In His wisdom, the Lord concealed the place where He buried Moses. God buried him, and God resurrected him and took him to heaven. This secrecy was to prevent idolatry. He against whom they rebelled while he was in active service, whom they provoked almost beyond human endurance, was almost worshiped as God after his separation from them by death. For the very samereason, He has concealed the precise day of Christ’s birth, that the day should not receive the honor that should be given to Christ as the Redeemer of the world, one to be received, to be trusted, to be relied on as He who could save to the uttermost all who come unto Him. The soul’s adoration should be given to Jesus as the Son of the infinite God. Adventist Home Pg. 477.
But God would be pleased if the birth of His son were celebrated in the right way. The focus of Christ's birth is not to please and indulge in self-gratification. If our minds can be shifted to Christ and His mission by involving ourselves in charitable donations and gifts to the needy indeed, how much money would be saved and far from wasted.
God would have us complete His mission and showcase His Love to humanity rather than waste our means on needless expenses.
