When Paul uses the language of God being “for us,” he speaks of it in the context of what Christ has done for us in history. For example, in Romans 8:31-32, he says, “If God is for us, who can be against us? He who did not spare his own Son but gave him up for us all, how will he not also with him graciously give us all things?” Not sparing his Son is the act that secures God’s being 100% for us forever.

So was God 100% for us from eternity because we were elect? In one sense, yes. It was 100% certain that he would bring us to faith and save us. But when I ask the question, “When did God become 100% for us?” I mean more than: “When did it become 100% certain that God would save us?” I mean: “When did it happen that God was for us and only for us? That is, when did it happen that the only disposition of God toward us was mercy? Or: When did God become for us so fully that there was not any wrath or curse or condemnation on us, but only mercy?

The answer, I still say, is at the point when, by grace, we saw Christ as a supremely valuable Savior and received him as our substitute sacrifice and substitute righteousness. In other words, it happened at the point of justification. The implication of this is that all our works, all our perseverance, all our continuing faith and obedience does not cause God to be 100% for us, but is the result of his being 100% for us.

Paul’s logic in Romans 8:32 is that because God gave his Son to die for us therefore he will give us all things with him. That is, God will see to it that we persevere to the end not only because we are elect, but because Christ died for us and we are in Christ. That is the logic of 1 Corinthians 1:8-9: “[God] will sustain you to the end, guiltless in the day of our Lord Jesus Christ. God is faithful, by whom you were called into the fellowship of his Son, Jesus Christ our Lord.” The call is mentioned as the ground of God’s faithfulness to sustain us to the end.

Therefore, exult in the truth that God will keep you. He will get you to the end because in Christ he is 100% for you. And therefore, getting to the end does not make God to be 100% for you. It is the effect of the fact that he is already 100% for you.

Glorying in the gospel with you,

Pastor John
