Are you really a Christian? Examine yourself and test yourself.
Examine- Ask the Lord to show you where you need to improve.
Test- Just because you have examined something and found it good does not mean it will work. You need to test it (or yourself).
Presumption- Do not make presumptions. Do you find fault in others while overlooking your own? Take care of your own faults first.
Do you think about heaven? Will you be content just making it into heaven, or do you want to have many crowns to lay at Jesus’ feet?
