At each worship we sing certain songs that ask for mercy and blessing, praise God for who God is and what God has done and celebrate what Jesus did among us. There are also readings of scripture, singing songs we select, prayers, a sermon and usually the sharing of bread and wine (or without alcohol if you prefer) according to the story of what Jesus instructed.
They are included in the assembly of worship and the sharing of the meal. There may be a special activity for them during part of the service. Most likely just during the time the sermon is being given. There are also crayons, coloring books, sheets with activities and so forth for them.
Both churches have large parking lots.
You may dress as you like. We nearly all dress very casually.
There are ushers (to help show you around and give you worship stuff) and greeters to answer your questions. Give us your contact information so we can keep in touch. There is usually a fellowship time after with refreshments.
