1 Corinthians - Don’t you know that you yourselves are God’s temple and that God’s Spirit dwells in your midst? If anyone destroys God’s temple, God will destroy that person; for God’s temple is sacred, and you together are that temple.
In three of the gospels, Jesus quotes His Father from Isaiah 56:7. I’ve always heard it said that if something is repeated in the Bible multiple times it is important. So even though the “Jerusalem’s great temple” is gone, God lives inside of us. We, His people, are the temple of the Holy Spirit.
Because we are the temple of God or the house of God doesn’t that give Him the right to name us? He could have called us the house of praise and worship, the house of bible study or fellowship. All of which aren’t bad things they are good things. But, God called us to be a House of Prayer for all nations.

In 1 Thessalonians 5:17, the Apostle Paul directs all believers to "pray without ceasing." Did Paul really mean that we should give up all other activity and only give ourselves to prayer? That we should pray 24/7? If we did, we wouldn't last very long. We need sleep. Most of us need to work to earn a living.
Obviously, it cannot mean we are to be in a head-bowed, eyes-closed posture all day long. Paul is not referring to non-stop talking, but rather an attitude of God-awareness and God-surrender that we carry with us all time. Every waking moment is to be lived in an awareness that God is with us and that He is actively involved and engaged in our thoughts and actions.
It’s also about our due diligence. Our persistence isn't to convince God to act but to keep active the lines of communication so that we know when He is prodding us into action. This is nowhere more evident than in the prayers we offer for the salvation of those around us who need a relationship with God. We know that God desires their salvation (2 Peter 3:9). All He is waiting for is a receptive heart and someone willing to deliver the good news. Might that someone be you?
