Therefore the law was our tutor to bring us
to Christ, that we might be justified by faith. 25 But after faith has come, we are no longer under a tutor.
26 For you are all sons of God through faith in Christ Jesus. 27 For as many of you as were baptized into Christ have put on Christ. 28 There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus. 29 And if you are
Christ’s, then you are Abraham’s seed, and heirs according to the promise. Gal 3
Keep in mind that John’s baptism was a baptism of repentance. He told the people to believe in the one coming after him, that is, in Jesus. Acts 19:4
Salvation is by grace through faith—and this is not from yourselves, it is the gift of God— Eph 2
Obviously if a person has not repented, turned to God, to be belong to another, to Christ Jesus who was raised from the dead, such person is fruitless, dead in transgressions and sins.
If Christ has not been raised, your faith is mere delusion [futile, fruitless]; you are still in your sins.
But Christ has indeed been raised from the dead, the firstfruits of those [baptized unto His death] who have fallen asleep. 1 Cor 15:17-20
He chose to give us a new birth through the word of truth, that we might be a kind of firstfruits of all he created James 1:18
We ourselves, who have the firstfruits of the Spirit, eagerly for our adoption to sonship; Rom 8:23
Stand Firm In The Faith
But we ought always to thank God for you, brothers and sisters loved by the Lord, because God chose you as firstfruits to be saved through the sanctifying work of the Spirit and through belief in the truth. 2 Thess 2:13
