You misinterpreted Acts 13:48. Christians, once saved, are ordained to good works and to witness and to eternal life.

No, the context is clearly evangelism of non-believers and not discipleship of believers. "Belief" in the context of the passage can in no way be substituted with "good works" or "witness" as you assert.

God knows who will be saved, but he does not choose.

If that were true, it would be tragic since no one would choose God had God not chosen them first. Scripture is clear in that regard

His eternal purpose is to have a people that are faithful without being chosen.

No, His eternal purpose is His own glorification. One of the ways He accomplishes that is exercising His sovereignty in salvation. It is human (sinful) nature and human pride that rebels against the idea that we do not have ultimate control of our salvation.

“No, His eternal purpose is His own glorification. One of the ways He accomplishes that is exercising His sovereignty in salvation. It is human (sinful) nature and human pride that rebels against the idea that we do not have ultimate control of our salvation.”

Your belief is Calvinistic and incorrect. Calvinism appeals to human pride in the belief that God picks and chooses who is saved, which is a lie. Unfortunately, this belief is pervasive in many “modern” churches due to John Calvin’s heretical beliefs which give excuses to those who do not witness for Christ.

God’s eternal purpose is much more than his own glorification. Read Revelation chapter 21 verse 6-8 “It is done”. God is proclaiming he now has his people that are faithful and have chosen him over the world.
