Acts 13
47 For so the Lord has commanded us:

‘I have set you as a light to the Gentiles,
That you should be for salvation to the ends of the earth.’ ”

48 Now when the Gentiles heard this, they were glad and glorified the word of the Lord. And as many as had been appointed to eternal life believed.

Appointed: (of a time or place) decided on beforehand; designated.

MOST of the interpretations say appointed. International Standard Version even says destined!
Say what?

I found a paper written about this with a good explanation:

The word appointed in most translations of Acts 13:48 is a translation of the Greek verb tassō. The leading dictionary of NT Greek gives as the first meaning of this word “to bring about an order of things by arranging, arrange, put in place” (BDAG, p. 991b).

The New International Dictionary of New Testament Theology article on tassō (vol 1, p. 476) reminds us of the military uses of this word: “its first meaning is military: to draw up troops (or ships) in battle array, and so to post or station them.”

The idea of arrangement and positioning fits well in Acts 13:48 too. An overly literal translation would be something like, “As many as had been arranged [or positioned] for eternal life believed.” We might paraphrase this as follow: “As many as had been prepared for eternal life believed.” When one makes arrangements for something, he prepares for it. Troops arranged in battle array are prepared to fight.

So a good translation would be:
God’s Word Translation:
The people who were not Jews were pleased with what they heard and praised the Lord’s word. Everyone who had been prepared for everlasting life believed.

God MUST prepare your heart through the Holy Spirit to receive salvation.
John 6:44 says
No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
