Jesus Christ, by His Holy Spirit can enter our hearts and be at home there.
“To be strengthened with might by His Spirit in the inner man; that Christ may dwell in your hearts by faith.”
(Ephesians 3)
“If a man love me, he will keep my words: and my Father will love him,
and we will come unto him, and make our abode with him.”
(John 14:23)
We ought to prepare a place for God in our hearts.
1 Corinthians 6:19 KJV
What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
What a privilege, to welcome Christ in our heart, to serve and fellowship with Him.
