The Suffering Servant is Israel personified, thus having no direct connection to Jesus.
Again, serious theologians know this, but Pastor Joe may not.
Reminds me of something Billy Graham once wrote, namely that the Christian message is simple enough that even one dull-of-mind can understand but complicated enough to turn theologians' hair grey.
The suffering servant is not Israel personified because while Israel is described as a servant, there are verses that describe the servant as distinct from Israel. Who Is The Suffering Servant? Israel Or Jesus?
The servant in prior chapters is distinct from Israel. There are several discourses about the servant in the later chapters of Isaiah, the NASB titling the chapters ‘God Helps His Servant’ (chapter 50), ‘The Exalted Servant’ (chapter 52:13-15) and finally ‘The Suffering Servant,’ (chapter 53). One can hardly blame the rational man for thinking that these are all the same figure. Beginning in Isaiah 49:5, the servant is talking, and he says “The Lord, who formed me from the womb to be his servant, to bring Jacob back to him, so that Israel might be gathered to him.” This servant seems to be one who is distinct from the nation of Israel.
