The Shunammite woman wanted to make a room for Elisha. The room was to be a resting place for the man of God. Elisha represents the presence of God, therefore the room was to be a habitation (a place to live in / a dwelling place) for the presence of God.
2 Kings 4:10 NKJV
“Please, let us make a small upper room on the wall; and let us put a bed for him there, and a table and a chair and a lampstand; so it will be, whenever he comes to us, he can turn in there.’ ”
The first step in preparing a place for God is repentance. A person becomes the temple of God at salvation because the Holy Spirit comes to reside (to live in) the believer.
Ephesians 2:19-22 NKJV
“Now therefore, you are no longer strangers and foreigners, but fellow citizens with the saints and members of the household of God, having been built on the foundation of the apostles and prophets, Jesus Christ Himself being the chief cornerstone, in whom the whole building, being fitted together, grows into a holy temple in the Lord, in whom you also are being built together for a dwelling place of God in the Spirit.”
The Spirit of God (Holy Spirit) lives within every Christian. We are to be holy because God is holy. If we do not keep our temple clean (holy, pure) the presence of God will not stay. God’s presence will not be where there is sin.
2 Corinthians 6:14-18 NKJV
“Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? And what communion has light with darkness? And what accord has Christ with Belial? Or what part has a believer with an unbeliever? And what agreement has the temple of God with idols? For you are the temple of the living God. And God said: ‘I will dwell in them
And walk among them. I will be their God,
And they shall be My people.’
‘Come out from among them
And be separate, says the Lord. Do not touch what is unclean,
And I will receive you. I will be a Father to you,
And you shall be My sons and daughters,
Says the Lord Almighty.’ ”
