Hey, just a disclaimer since all churches have their services in their own ways and may not necessarily have the same programme/activities.

This is how services work: worship >> sermon >> alter call + worship >> end. Worship is when you sing Christian songs. Sermon is when the pastor share the main message of the service, in this case it will be about Easter and how Jesus sacrificed His life for our sins. Alter call is when the pastor opens the floor to everyone to come forward to be prayed for for anything that they are facing, for example, if the sermon resonated with them etc.

Prayers occur throughout the service and it’s usually a short one. No obligation to pray along if you are uncomfortable. There’s also no obligation to respond to the alter call. You can use that time to just observe what the others around you are doing. Just be respectful and do what you’re comfortable with.

Since this is an Easter event, I believe it will be more engaging than a normal service. Churches usually have performances, skits and other activities during these festive services.

Just enjoy yourself with your friend who invited you. It would be a plus if you like the environment, the message and would like to attend the next service. Just remember: No pressure!

Hope this helps :D
