Mockings appear to be trials for which the mockers have apparent evidence, for instance the treatment of Sampson by the Philistines. They believed that having cut off his hair his strength had left him permanently, and they therefore made sport of him at the sacrifice to Dagon their god.
We have limitations put on us. We are enclosed by all sorts of problems that shut us up. We have no access to the public media and are therefore limited. But the heroes of faith continue to trust and serve God even when imprisoned; God can overrule. The Christian life is also a life of constant resistance. We are always to resist by faith. We have always to take account of the problem and the effect on the cause.
