Paul received a clear vision of a man calling him to preach in Macedonia. Paul had been inquiring of God. Several doors had closed in front of him. He needed to know which way to go. He needed a fresh move of the Spirit.
In Macedonia, he found a group of ladies worshipping on a river bank. One of these ladies, Lydia, a seller of purple, was converted with her household. This new group of Christians later made up the first church in Europe. They met regularly in Lydia's home. I bet they were glad Paul kept listening!
If it were me, with that vision, I would have been looking for a MAN in Macedonia, not women! Not because I'm sexist. I just get tunnel vision when I feel I have clear direction as to the way God would have me go. I don't keep my heart and mind open. I don't keep listening like Paul.
A dynamic relationship with God requires I have a willingness to constantly change my plans to suit God's will for my life.
It means I must constantly adjust to stay on the right road. It means I must never insist that God follow me down a road of my own choosing. It means I must constantly look and listen for him. It means I must stay tuned into HIS frequency. It means I must trust spirit over flesh.
If I do not, I find myself far up the road ahead of God; back behind; or, on a road that takes me entirely away from him. I don't want to be on THAT road again. Been there. Done that.

I ain't going back.
Here I am, Lord. I'm listening again.
