I see a wisdom in this, but not perhaps the way you meant.As the Western world falls away, the sign gifts might become more important.
As people fall farther from a pure faith, they will cling more needy to seeking a sign.
God gave signs and wonders to Jesus, and to the Apostles, and other early evangelists, and there was no question about it. Now we question signs and wonders why? Because we do not see them.
People make many claims, but it's hard to hide when you're shadow heals everyone upon whom it falls, as Peter's did. Paul's cloths that were sent out with healing powers, not the lying nonsense of TV fakers, but the real deal.
If the real thing were happening, there would be no question.
But when I look at signs and wonders at the end of the age, I see that there will be lying signs and wonders given to deceive. So I really caution about seeking after signs and wonders, and instead preach faith, and trusting Him by His Word. Faith comes by hearing the Word of God, not by seeing a sign.
Much love!
