But I will stay on at Ephesus until Pentecost, because a great door for effective work has opened to me, and there are many who oppose me. (1 Corinthians 16:8-9, 12-30-12)

Opportunity and opposition. Not mutually exclusive. Matter of fact they often come together.

Which only makes sense. Satan is going to oppose anything with the probability of being significant.

Matter of fact, I wonder if opposition, instead of being a sign to stop, is often a marker of high potential. If Satan might start providing resistance to keep us out of a place before we even recognize the opportunity.

[Father, help me to see through the opposition to the opportunity, and give me the wisdom to see when an opportunity is truly from You.]
