We come together to store up godly knowledge and learn to become doers of the Word. We believe godly knowledge is profitable to us and will make us wise.

Wise people store up knowledge, but the mouth of the foolish is near destruction.
Proverbs 10:14

But be doers of the word, and not hearers only, deceiving yourselves.
James 1: 22

It is also a time of gathering of saints to enrich and cherish each other. We expect God to demonstrate His Word with signs and wonders following.

Not forsaking the assembling of ourselves together, as is the manner of some, but exhorting one another, and so much the more as you see the Day approaching.
Hebrews 10: 25
