" .. According to the Good Pleasure Which He Purposed in Himself, .."

God causes all things to work together for His glory and our good, that is, all who love Him.
It is the peace that surpasses all understanding, which we experience, when we know our Lord is sovereign over every hair on our head, and every step that we take. He is a Father, who will love His children to the uttermost, and to the very end. And our Lord and Savior, Jesus Christ, has promised to be with us, even "to the end of the age".

I was reading tonight where King Hezekiah was very ill (2 Kings 20:1), and God told him he was going to die. This caused him to weep bitterly to the Lord. And the Lord heard him, and granted him 15 years of life. Not 14 more years, or 16, or even, "I'll heal you, and then we'll see how long you live", type of deal. Nope, he lived 15 years on the "nosey".
That's how a sovereign God works with His children. He was sovereign over every minute of Hezekiah's life, but at the same time God works within our life's problems, struggles, and even sins. He's a good Father, and a faithful Friend.

When I read that Hezekiah "wept bitterly" (ver. 3), I thought of the Apostle Peter, for Peter had a night when he "wept bitterly". After the passover meal Peter told Jesus that he would never deny Him, though everyone else may, he would never deny Jesus.
Jesus looked at Peter, and told him he was going to deny Him three times, before the cock crows in the morning. Not 2 times, or 4, or even something like: "Peter, I'm praying that you won't deny Me, and I hope you can be strong, but we'll have to wait and see" kind of deal. No, it was exactly three times, and then the cock crowed, and Peter's heart became heavier than he ever knew, and he wept bitterly. Jesus wanted this to happen to Peter, for Peter's good.

So take courage. As God worked in Hezekiah's and Peter's life for their good, He will work in similar ways within our lives as well; for all those who love Him, and trust Him, that is.
I guess the honest question we all need to wrestle with is: "Do you love Jesus?"
