John 1:12 (KJB)But as many as
received him, to them gave he
power to become the sons of God,
even to them that believe on his name: Received - Take hold of, grasp, or obtainPower - Authority Those of Israel did not receive Him because they did not know Him. Now here John turns to a different aspect of receiving Him, In the previous verse, it was speaking of receiving Him as the Messiah on a national level but here John is now making the receiving of the Lord Jesus Christ a personal thing and not something which is done nationally. He now turns to the real way a person receives the Lord Jesus Christ and that is for salvation. When a person receives the Lord Jesus Christ as their personal savior, they are given the authority or the right, to claim that they are a child of God. It is one of the cardinal tenets of salvation. Now I have heard this verse used by many who believe in free will, that is, they believe that all you have to do is believe on the name of the Lord Jesus Christ and you will be saved. Now there is a problem with espousing such a belief. First of all, believing is a work which means that a person is doing a work to initiate their salvation and this is not taught in the Scriptures. Secondly, a person is spiritually dead so it will be impossible for a spiritually dead person to activate some type of belief. (Eph 2:5 KJV) Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved
The dead can do only one thing and that is remain dead unless they are resurrected. There is only one way a person can receive the Lord Jesus Christ as their savior and that is a qualified response. First of all, a person becomes saved through grace and they receive it without asking for it. Secondly, that person is indwelled by the Holy Spirit and are given faith as a fruit of the Spirit. (Gal 5:22 KJV) But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Now that they have faith, they may believe because they are now spiritually alive. Faith is the basis of belief and only the saved person can believe since they are grounded in faith. The spiritually dead do not have faith since they are not indwelled by the Holy Spirit. This is why many who claim to be saved are not saved because their faith is sourced only in words and not in the Holy Spirit.
John 1:13 (KJB)
Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. This verse continues the thread from verse 12. Here is a clear statement that a person is not saved by any act of the flesh, which would be any type of work such as those under the law. Many even believe that a person can exercise their will to be saved, that is, a free will to be either accept or reject the Lord Jesus Christ. The unbeliever already rejects the Lord Jesus Christ because of them being spiritually dead. They are in the same boat as the Pharisees, they did not receive Him because they did not recognize Him owing to spiritual deadness. The will of man is only limited to what he can do in the flesh and even that is severely limited. Have you ever seen anyone cure a cold by using their will? The will of man cannot cure a cold never mind will themselves into Heaven. However, this verse ends up stating that those who are born again, or saved, are saved by the will of God. It is God’s will who initiates salvation in the life of a believer. If God wills a person to be saved, then it will happen according to His timetable. I became saved at 27 years old. I wasn’t cognizant of being born again until God saved me. Salvation, then, is according to God’s will and no matter how many words a person says, they cannot save themselves. We only respond to what God initiates.https://www.scionofzion.com/gospel_of_john_1_11_15.htm
