Isaiah 56:7 (New King James Version)
Even them I will bring to My holy mountain,
And make them joyful in My house of prayer.
Their burnt offerings and their sacrifices
Will be accepted on My altar;
For My house shall be called a house of prayer for all nations.”
Praying always with all prayer and supplication in the Spirit, being watchful to this end with all perseverance and supplication for all the saints—
Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.
1 Thessalonians 5:17-18
17 pray without ceasing, 18 in everything give thanks; for this is the will of God in Christ Jesus for you.
