Notice it went from “THEY” in all the previous verses, to “WE” HERE.
Who is “WE”? Who wrote ACTS? Luke!
So in Troas, where God led them without them realizing it, they meet up with Luke and he joins them.
One theory is that Luke was encouraging Paul to go to Macedonia, but was reluctant. God gave him a vision to convince him to go.
Again, we don’t know, but it took a vision from God to get Paul to go there.
Up to now, Paul has been using his own plans to accomplish God’s work.
None of which have been fruitful.
How often have we tried things that in our minds and with all outward appearances seem to work, only to fail or not even get off the ground?
The point is, we should still pray and plan. And if those plans are somehow stopped, don’t quit, get another plan, and another until God gets you where He wants you.
There's a sermon to preachers that says, "I’d rather see a pastor try 100 things that all fail then to never try anything for fear of failing."
A closed door or a stopped plan is not sin.
