When God opens a door to use you in ministry, adversity should be expected.
For a great and effective door has opened to me, and there are many adversaries. 1 Corinthians 16:9 (NKJV)
Dear friends, don’t be surprised at the fiery trials you are going through, as if something strange were happening to you. Instead, be very glad—for these trials make you partners with Christ in His suffering, so that you will have the wonderful joy of seeing His glory when it is revealed to all the world. 1 Peter 4:12-13 (NLT)
