John 1:12 - The Born Again Experience!!!

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: John 1:12 (KJV)

As many as received. John here brands as error the belief that simply
because Christ died for all men, all will therefore be saved. Marked equally
false is the belief that God predestines certain men to be saved and others
to be damned. John emphatically declares that the decisive factor lies with
men themselves-"as many" as receive and believe are granted access to
sonship.
Power. rightly translated "authority." Because of sin man had lost all his
rights and deserved the penalty of death. The plan of salvation restored
man's opportunity to know God and to choose to serve Him.
To become. God does not arbitrarily make men His sons; He enables them to
become such if they so choose.
On his name. To believe on the name of Christ is to appropriate the
provisions of salvation in Christ Jesus. [SDA Commentary]

The word "believe" essentially means "trust" and suggests not just an
intellectual agreement with facts, but a committed reliance upon the truth
concerning Jesus. [New Bible Companion]

All who welcome Jesus Christ as Lord of their lives are reborn spiritually,
receiving new life from God.  Through faith in Christ, this new birth
changes us from the inside out - giving us new attitudes, desires, and
motives.  Being born makes you physically alive and places you in your
parents' family.  Being reborn makes you spiritually alive and puts you in
God's family.  Have you asked Christ to make you a new person?  This fresh
start in life is available to all who believe in Christ.  [Life Application

The same Power that created the universe (v.3) is available to create a new
life from our shattered hopes.  The Light of life that exposes and drives
away the darkness of the human race (v.4-5) is the same Light that brightens
the dark corners of our world.  This source of all life and true Light of
the world is the source of our recovery.   Eternal life and true recovery
are ours when we believe what God says, renounce our tendency to do things
our way, and receive the one whom God sent to help us (v.11-13).  Life

People are not naturally children of God but can become so by receiving the
gift of the new birth. [Bible Knowledge Commentary]

The name of a certain younger man was mentioned to a famous teacher, whose
student the younger man claimed to be. The older man answered: "He may have
attended my lectures, but he was not one of my students."  There is a world
of difference between sitting in a teacher's class room and being one of his
students. There can be contact without communion; there can be relationship
without fellowship.  All men are the sons of God in the sense that they owe
to him the creation and the preservation of their lives; but only some men
become the sons of God in the depth and intimacy of the true father and son
relationship. . . . This sonship does not come from any human impulse or
desire or from any act of the human will; it comes entirely from God. We
cannot make ourselves sons of God; we have to enter into a relationship
which God offers us. . . .But there is a human side to this. What God
offers, man has to appropriate. A human father may offer his son his love,
his advice, his friendship, and the son may refuse it and prefer to take his
own way. It is so with God; God offers us the right to become sons but we
need not accept it. [Barclay Commentary]

He who is made a child of God enjoys the greatest privilege which the Divine
Being can confer on this side eternity. (Adam Clarke Commentary)

Is my knowledge of Jesus born of internal spiritual perception, or is it
only what I have learned by listening to others? Have I something in my life
that connects me with the Lord Jesus as my personal Saviour? All spiritual
history must have a personal knowledge for its bedrock. To be born again
means that I see Jesus. [My Utmost for His Highest ]

John the Baptist was telling his audience Jesus was coming. He pointed ahead
to Jesus and called people to repent. Jesus would do more; He would not only
call the people to change their sinful ways, but also give them the power to
do so. Why speak of fire? Scripture is always to the point. What does fire
do? It does three things: gives light, warmth and consumes something. When
the Spirit comes into your life, count on these three things: into the light
He brings dark habits and they must be changed; He brings comfort like
warmth where there hasn't been comfort; and lastly, He consumes. What is
consumed?  As the believer willingly confesses and releases a portion of
his/her life to God's control, this portion of sin/weakness is consumed like
the sacrifices of old. And like those sacrifices, something is given in
their place. It is the control of God's Spirit; strength to the believer,
glory to God. Desire the Fire and be all you can be, in Jesus Christ!  [In
His Time; Walk With Wisdom]

        Satan had claimed that it was impossible for man to obey God's
commandments; and in our own strength it is true that we cannot obey
them. But Christ came in the form of humanity, and by His perfect
obedience He proved that humanity and divinity combined can obey
every one of God's precepts.
        "As many as received Him, to them gave He power to become the sons
of God, even to them that believe on His name." John 1:12. This
power is not in the human agent. It is the power of God. When a soul
receives Christ, he receives power to live the life of Christ.
COL314

"As many as received him, to them gave he power to become the sons of God,
even to them that believe on his name." Shall we not, then, give to Christ
that which He has died to redeem? If you will do this, He will quicken your
conscience, renew your heart, sanctify your affections, purify your
thoughts, and set all your powers at work for Him. Every motive and every
thought will be brought into captivity to Jesus Christ. 7BC909
