For me, I think it's a distinction between realizing that God can and does work in that way today and being open to recognizing that work in my life, versus expecting that particular manifestation to occur in my life. Many biblical figures experienced the leading or guide of angels, but many others did not.Whether that particular form of God's leading and guidance occurs in my life or not isn't up to me, so I don't see a basis for expecting or not expecting it. My expectation and faith is planted in the knowledge that God loves me, orders my steps, works for my good, and sanctifies me by His grace. I 100% expect that to occur every day of my life. But as for the particular means in which it occurs, I don't see a reason to expect one manifestation over another, if that makes sense.
