Main point summary
Given the fact of God electing who He wills, we conclude that the Gentiles have attained righteousness by faith, but Israel has not attained to the law of righteousness, just as is written that the honor of righteousness comes through believing in Christ and not by shamefully stumbling in pursuit of establishing ones own righteousness.
What shall we say then?
who did not pursue righteousness,
have attained to righteousness,
even the righteousness of faith;
pursuing the law of righteousness,
has not attained to the law of righteousness.
Why? Because they did not seek it by faith,
but as it were, by the works of the law.

and rock of offense,
And whoever believes on Him
will not be put to shame.”

Application It is well possible for you and me, we who may not be Israelits, to walk in the same trait as they do. We might be searching for ultimate righteousness or perfection in the wrong way and at the wrong place. If I'm looking to myself to attain perfection, be it in the perfect job, house, appearance, cleverness, friends or family etc, then I'm setting myself up for misery because ultimate things are found in God alone. Sad to say, but we and this world is corrupted. Accepting God's perfect gift of eternal life in Christ is the ultimate perfection all our souls long for. All other things are gifts to be enjoyed till we see Him, who is the reality of the pleased things which He has given us for our enjoyment. A tast of joy just for a season now, but then with Him in full for all eternity.
