EVERYTHING that God does was ALWAYS in His plan.
BUT, God did NOT reveal EVERYTHING about His plan all at once.

The blindness of Israel is TEMPORARY. See Romans 11.
Rom 11:25 (AKJV/PCE)
(11:25) For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
