God opens doors of opportunity for us all the time. It usually requires faith to step through them. Paul had that chance, and he wrote the church about it.
For the present, I'm staying right here in Ephesus. A huge door of opportunity for good work has opened up here. (There is also mushrooming opposition.) - 1 Corinthians 16:8-9 (The Message)
I find it interesting that in the same breathe he spoke of opportunity he mentions the opposition. Just because god opens the door doesn’t mean we shouldn’t expect trouble from the world. (Remember they are against Him.) Even though the Adversary is against God’s work – His people should be more the willing to step up and through these God moments.
God is already there and wants us to be there working with Him! It will be a chance to use our spiritual gifts, and show our obedience.
Be wise today and always – step through any door God opens.
