That is then - future - but what about now?
If you are saved, then it was by grace before the foundation of the earth. And if you are saved now, then you will persevere to the end. If you fall away, then you were never really saved.
So although from a temporal standpoint, your salvation is secured on earth by grace through faith, from God’s viewpoint you were saved from the foundation of the earth.
Are you concerned for your own salvation, or are you speculating as to the salvation of others?
By whose power have you been saved? Is it by the power of your own temporal decision or actions or works, or by the power and grace of God alone?
What’s your point? Are you troubled over a friend and should we offer our prayers for them? If so PM me and we can get a prayer request thread going.
