Why did Jesus perform signs and miracles over and over in His earthly ministry?
He performed signs and miracles over and over for the benefit of the Jew, and His sole reason was to convince Israel of who He was. The Jewish mentality sought a sign, so those miracles confirmed His identity during His earthly ministry.
Les teaches that over and over God performed signs and miracles for the benefit of the Jew. When He came in His earthly ministry, that was the sole reason for His performing the signs and miracles over and over: to convince Israel of who He was. Paul later brings this into the New Testament account, showing that the Jew mentality was still “show me a sign,” while the Greeks were hung up on intellectual philosophy. Paul says he adheres to neither approach, but preaches Christ crucified.
