When Christ enters a human heart He cannot be hidden: for soon his Spirit begins to breathe out in all the words and actions and life of the new follower.
When He enters a home he cannot long be hidden, for the home is changed – worldliness, bitterness and sin giving place to prayer and praise, to the spirit of love and gentleness, and to purity and holiness. When he enters a community He cannot remain concealed. The stories of missionary work illustrate this … Christ will always reveal His presence in this world.
(J. R. Miller)
"Therefore the Lord himself will give you a sign: The virgin will be with child and will give birth to a son, and you will call him Immanuel."
Isaiah 7: 14
