Jesus said, "My house shall be called a house of prayer for all nations."

What are we to do in church? Pray, intercede, bring the nations before God, heal the sick, exalt the Lord and not use His name to trade or do business. God's promise to us,

What then shall we say, brothers and sisters? When you come together, each of you has a hymn, or a word of instruction, a revelation, a tongue or an interpretation. Everything must be done so that the church may be built up. 1 Corinthians 14:26

Be very careful, then, how you live —not as unwise but as wise, making the most of every opportunity, because the days are evil. Therefore do not be foolish, but understand what the Lord’s will is. Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit, speaking to one another with psalms, hymns, and songs from the Spirit. Sing and make music from your heart to the Lord, always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ. Ephesians 5:15-20
