Charles Spurgeon Commentary Isaiah 49:5

"And now saith Jehovah that formed me from the womb to be his servant, to bring Jacob again to him, and that Israel be gathered unto him (for I am honorable in the eyes of Jehovah, and my God is become my strength);" — Isaiah 49:5 (ASV)

And now, saith the LORD that formed me from the womb to be his servant, to bring Jacob again to him, Though Israel be not gathered, yet shall I be glorious in the eyes of the LORD, and my God shall be my strength.

Even though the Jews still reject the Messiah, their sin does not affect his honour. His glory is still as great as ever it was in the esteem of the Most High.

And now, saith the LORD that formed me from the womb to be his servant, to bring Jacob again to him, Though Israel be not gathered, yet shall I be glorious in the eyes of the LORD, and my God shall be my strength.

Even though the Jewish nation is not yet gathered to Christ, his labour was not in vain. God will not suffer his Son to spend his strength for nothing.
