Visitor Visa - B2

Hi All. I hope someone can help me regarding my plan to re-apply for a US Visa next week and please provide a feedback and advise. Thank you in advance.

I am a 27 male from the Philippines, Single and have worked for a BPO for more than 5 years. I applied last June 2016 but was rejected. Here's how the interview went:

VO: Good morning!
Me: Hi, Good morning!
VO: Why are you going to the US?
Me: I was invited as a guest by (a church in the US) to participate in many of their activities and events
VO: May I see the invitation?
Me: (gave her the invitation but she did not read it)
VO: Where in the US?
Me: Answered the City and State
VO: What's in it for you?
Me: I will become a pastor here after the training
VO: What's your job here?
Me: I am a Manager
VO: How long have you been in the BPO?
Me: Eversince or with my current employer?
VO: Eversince
Me: 5 years
VO: Who will pay for your trip?
Me: The church in the US will provide my meals, housing and transportation. Our local church will provide the plane ticket and my personal allowance. I have my own savings too.
VO: Unfortunately I cannot give you a visa. Thank you.
Me: Oh, okay, thanks.

Do you know what could be the reason of my denial? Next week, I am scheduled for an interview again. Lots have changed in my situation since last year. Here are the following:

-I am now engaged with my long time girlfriend
-I have resigned from my previous job and is now working full-time as a Pastoral staff for 9 months (I started one month after my visa was denied)
-Our house title is now in the process of being transferred to my name
-I have a business for 3 years now which I did not mention in the interview last year. However, that business is for a sweepstakes which might contradict my current job in our church.

Let me know your thoughts please. The more, the better. I will give you an update next week regarding the result of my interview so please respond with your tips and advise as soon as possible. I appreciate all your help. Thank you.
