1 Corinthians 2:14 has nothing to do with choosing God, it's about being able to recognize and understand spiritual things. Only those with the Holy Spirit are able to do these things.Choosing God is a choice that only those who have been born again spiritually will make. The natural man, according to 1 Cor 2:14 will not, and indeed, can not choose spiritual things, thinking them to be foolishness.
Salvation, in your first theory, according to Strong's concordance, means deliverance eternally, and saved, in your second theory means the born again person is delivered from not believing in spiritual things
You are using it with salvation when it has absolutely nothing to do with salvation.
Salvation comes by ""hearing"" the Gospel preached and believing.
