When a father puts gifts under the Christmas tree, it is not to compensate his children for doing their chores. That would make whatever is inside that wrapping paper a wage, not a gift. A gift is given voluntarily simply so the giver can show favor to the one receiving the gift, without any expectation of repayment. In the season of Christmas, we receive the gift of God. That does not simply mean we receive the gifts God gives. When we look into the manger, we see that God is the gift. Jesus, God and man, gives himself in sharing our humanity and freeing us for life eternal.
11 Both the one who makes people holy and those who are made holy are of the same family. So Jesus is not ashamed to call them brothers and sisters. … 14 Since the children have flesh and blood, he too shared in their humanity so that by his death he might break the power of him who holds the power of death—that is, the devil— 15 and free those who all their lives were held in slavery by their fear of death. (Hebrews 2:11,14-15)
