The word theology simply means the science of God. Understanding theology isn’t always easy, but to grasp the true meaning of Christmas you have to make one presupposition. Since Old Testament prophets write about the coming of a Messiah, human beings need to acknowledge their need for a Savior. The presupposition individuals must make is that you can’t save yourself. Without this realization, Christmas is just another holiday as a Savior is not sought out.
As it is written, None is righteous, just and truthful and upright and conscientious, no, not one. 11 No one understands [no one intelligently discerns or comprehends]; no one seeks out God. 12 All have turned aside; together they have gone wrong and have become unprofitable and worthless; no one does right, not even one! – Romans 3:10-12
In the passage above, the apostle Paul drives this point home to members of the church at Rome. Referencing an Old Testament prophet, Paul explains that no one is perfect. No matter how highly you may regard yourself, every day, week, month and year people stray from God’s law. Regardless of what disciplines, focus and safeguards are put into place, sooner or later you will break, cut corners or deviate from commands in the Bible.
For the wages which sin pays is death, but the [bountiful] free gift of God is eternal life through (in union with) Jesus Christ our Lord, Romans 6:23.
The best way I know to unwrap the theology of Christmas is through an illustration I learned from Evangelism Explosion. The passage above is part of a diagram using the Grand Canyon. Human beings are on one side of the canyon and God is on the other side. However, Jesus is offered as a free gift, dying on a cross to save mankind from sin. Those who accept the gift of eternal life through a personal relationship with God have access to cross this canyon by faith. This invisible bridge is in the shape of a cross. The moment Jesus was born, salvation and eternal life was made possible, 1 John 5:13. May these words sink in as Christmas Day approaches.
