therefore thus says the Lord God,
“Behold, I am the one who has laid as a foundation in Zion,
a stone, a tested stone,
a precious cornerstone, of a sure foundation:
‘Whoever believes will not be in haste.’
And I will make justice the line,
and righteousness the plumb line;
and hail will sweep away the refuge of lies,
and waters will overwhelm the shelter.”
Isaiah 28:16-17
Our purpose in worship is to edify the whole church
Pursue love, and earnestly desire the spiritual gifts, especially that you may prophesy. For one who speaks in a tongue speaks not to men but to God; for no one understands him, but he utters mysteries in the Spirit. On the other hand, the one who prophesies speaks to people for their upbuilding and encouragement and consolation.
1 Corinthians 14:1-3
We must speak clearly
So with yourselves, if with your tongue you utter speech that is not intelligible, how will anyone know what is said? For you will be speaking into the air.
1 Corinthians 14:9
Our minds must be engaged in worship
What am I to do? I will pray with my spirit, but I will pray with my mind also; I will sing praise with my spirit, but I will sing with my mind also.
1 Corinthians 14:15
We expect and welcome unbelievers to worship with us
But if all prophesy, and an unbeliever or outsider enters, he is convicted by all, he is called to account by all, the secrets of his heart are disclosed, and so, falling on his face, he will worship God and declare that God is really among you.
1 Corinthians 14:24-25
God is a God of order and peace, so the worship service should be orderly and peaceful
For God is not a God of confusion but of peace.
1 Corinthians 14:33a
But all things should be done decently and in order.
1 Corinthians 14:40
Submission to the apostles is mandatory
If anyone thinks that he is a prophet, or spiritual, he should acknowledge that the things I am writing to you are a command of the Lord. If anyone does not recognize this, he is not recognized.
1 Corinthians 14:37-38
