First Baptism Service Scheduled for Sunday

Just finished preparing to preach for Sunday and I am very excited because we will be having our first Baptism service. 
I plan, Lord willing, to preach on Baptism (Water and Spiritual Baptism).

Here are the questions I intend to answer... 

1. Who is Your Spiritual Family?

2. Can I Change Families?

3. What’s the Difference Between Families?

4. What Makes the Change Effective?

5. What Does Water Baptism Do?

Do you know where I'm going with each question?
