One way is that Christians will go to church to praise God for creating everything due to his full power. For example, they sing songs such as 'Our God is a great big God'. The Christians praise God for the creation of the universe and the wonders of the universe.
The second way is they will pray. For example, Christians will pray for God for their relatives' health if they are seriously ill in the hospital. They do that because they think God is 'all-powerful' and will heal their relatives. "Nothing is to hard for you"
