Charles Spurgeon Commentary Luke 2:27

"And he came in the Spirit into the temple: and when the parents brought in the child Jesus, that they might do concerning him after the custom of the law," — Luke 2:27 (ASV)

And he came by the Spirit into the temple:

Men who have the Spirit will be led by the Spirit. Simeon came into the temple at the right moment. Just when a young man was entering, with his wife and newborn child, He came by the Spirit into the temple.
