Can My Pastor Instuct Me To Marry A Sister In My Fellowship

As long as u av never thot about her in that light, i don't think its ok for u to go ahead and marry her. But just to be on the safe side, please go ahead and seek God's face concerning it. All the best. 

A few questions at the poster

1. Are you finanacially well off ?
2. Is your pastor aware of your financial status ?
3. Is the sister getting towards the dangerous age of thirties ?
4. Is your Pastor aware that you have somebody in your heart ?
5. What is the relationship between your pastor and the sister ?

The reason for these questions is simple: Just hoping your Pastor is not trying to match a sister to a brother he thinks has got it.

Your Pastor may hear from God but he is not God. If you are a christian, talk to God and let Him lead you to the right woman.
You are the one who will live with the girl you marry not your pastor. You therefore should be doubly sure of who you marry and not just rely solely on what your Pastor says. He is human and not infalliable.

All the same, pray about it and try being friends with the sister in question. Your pastor just might be right. I am not saying he is right.
