The Gospel in and of itself does not save anyone.
The person must believe the Gospel in order to be saved.
It is up to each person who hears the Gospel, whether of not to believe the Gospel.
It's a choice for each of us to make.
For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
John 3:16
- that whoever believes in Him should not perish
God does not force anyone to believe, if He did then all would believe, since it is not God's will that any should perish, but that all should come to repentance.
The Lord is not slack concerning His promise, as some count slackness, but is longsuffering toward us, not willing that any should perish but that all should come to repentance.
2 Peter 3:9
- not willing that any should perish but that all should come to repentance.
Repentance is where the person who hears the Gospel must choose to repent or not.
- Repent means to turn to God.
If you are called to
turn to God, then by default you are
called to turn from Satan as your lord.
The way that you express this obedience of faith, concerning the Gospel is to
confess Jesus as Lord.
This is what grants the
believer/obeyer of the Gospel, the forgiveness of sins.
This is plainly what the Lord Jesus Christ taught to and commissioned Paul to do.
15 So I said, ‘Who are You, Lord?’ And He said, ‘I am Jesus, whom you are persecuting. 16 But rise and stand on your feet; for I have appeared to you for this purpose, to make you a minister and a witness both of the things which you have seen and of the things which I will yet reveal to you. 17 I will deliver you from the
Jewish people, as well as
from the Gentiles, to whom I now send you, 18 to open their eyes,
in order to turn them from darkness to light, and from the power of Satan to God, that they may receive forgiveness of sins and an inheritance among those who are sanctified by faith in Me.’
Acts 26:15-18
Repent is about being transferred from the kingdom of darkness to the kingdom of God.
It's about changing who you serve, as your Lord.
The Gospel of the kingdom is about changing the kingdom your are in, by changing the lord you serve.
