The Apostle Paul said no calling without oppositions of some sort is an authentic calling. There is no such thing as an authentic ministry, an authentic anointing, and an authentic calling without problems or oppositions of some sort. Paul wasn’t intimidated in 1 Corinthians at Ephesus in spite of the oppositions that he had to endure.
A work that has a little opposition from the antagonistic system of Satan is one that is doing little work for the Lord. If the door is great, then the adversaries are many. If the door is little, then the adversaries are little. Great doors denote great adversary.
Every door that God has planned for your, there are adversaries waiting to shut the door and to stop you from going through. But the devil is a liar.
In Revelation 3:8, God said I have set before you an open door which no one can shut. This is your year to walk through NEW DOORS.
