But my impression is that any is very good and according to the timing God leads you into. I don't think this pastor is a real legalistic one. I think God wants our heart attitude and to see it demonstrated in real action of such prayer and fasting. I don't think a lot of petty details will be real crucial even to God.
If we were part of the same congregation, maybe it would be important, but I don't think all across the net it's that crucial. The unity of heart, mind and spirit is quite powerful in and of itself. . . . just my opinion.
Blessed by your question.
God's best to you.
