The following is from an email exchange that my home group leader had with another individual (shared with permission). This is what he had to say regarding paedo-baptism and its arguments for it from Scripture. This is also why I agree that infant baptism is biblical and have decided that this is what my wife ad I will practice when we have kids.
“1. Scriptures do command infant baptism directly. If the Bible is one
book and not segregated into two like the error of dispensationalism,
then Genesis 17 is a command to apply the sign of the covenant to the
children of believers–it is a command for the everlasting covenant,
which continues through Abraham to Christ in the new covenant. We see
this command continued in the New Testament with the covenant language
of Peter, “The promise is for you…and your children.” The promise
is not some hallow thing dependent upon your will. The promise is the
promise of the covenant, that God will be a God to you AND to your
children. This is reiterated in Scriptures in the promise of the New
Covenant, where Scripture says in Jeremiah 32,
38 And they shall be my people, and I will be their God. 39 I will
give them one heart and one way, that they may fear me forever, for
their own good and the good of their children after them. 40 I will
make with them an everlasting covenant, that I will not turn away from
doing good to them. And I will put the fear of me in their hearts,
that they may not turn from me.
and in Isaiah:
3 For I will pour water on the thirsty land,
and streams on the dry ground;
I will pour my Spirit upon your offspring,
and my blessing on your descendants.
13 All your children shall be taught by the Lord,
aand great shall be the peace of your children.
2. We do not disassociate baptism with faith in regard to Christ’s
infants. We believe in infant faith. The Scripture is clear on this,
from the faith of John the Baptist in the womb of his mother to the
words of David in Psalms 22:
9 Yet you are he who took me from the womb;
you made me trust you at my mother’s breasts.
10 On you was I cast from my birth,
and from my mother’s womb you have been my God.
Calvin called it the seed of faith which God gives to our children
from birth, which we believe is watered by baptism (baptism is used
throughout life to build their faith) and brought to maturity through
the covenant rearing and catechizing of the parent(s) and confirmed in
acceptance to the Table of the Lord. This is the basis for the belief
that troubled you. Presumed regeneration is a misnomer. The truth
that the book was trying to tell you is that parents are called to
believe in the covenant promises of God for their children. This
entails believing in the election of their children and believing that
God has implanted faith within them making them His children
(otherwise you must believe they are apart from God’s church and part
of the world and children of the devil). This must not override their
belief in the sovereignty of God, that God may, if he so chooses, have
any one of their children to be children of this world. But relying
upon His promises they are called to believe that condemnation is not
God’s intention for their children, but rather salvation is. This is
why David could rejoice that he would see his bastard child again, he
was clenching to the promises of the covenant, despite his
sinfulness–It is God who is faithful to the covenant; it all depends
3. Now let me send some questions back to you. One of the reasons I
became a paedobaptist is because of my trying to answer these
questions: Do you realize that not baptizing your children are
calling them children of the devil and His world? Do you realize that
not baptizing your children is not trusting in the promises of God for
your children? Do you realize that not baptizing your children is
denying them assurance that David had when he said, “from my mother’s
womb you have been my God”? Do you realize that neglecting baptism to
your children is saying that they are not children of God? Do you
realize that neglecting baptism to your children is to make the new
covenant less glorious than the old who included her children? Do you
realize that neglecting baptism to your children is saying that you
believe God has NOT chosen them? If God has not chosen them, then how
can they be saved? If God has not chosen them, then how can Jesus
love them? For Jesus loves the elect and he hates the wicked. Do you
realize that neglecting baptism to your children is saying that they
are faithless? Do you realize that neglecting baptism to your
children is depriving yourself of a key tool in covenantal rearing?
Do you realize that neglecting baptism to your children is telling
your children that your God is not their God?
4. Circumcision and Baptism are not meant to be one to one parallels.
One fulfills the other. Baptism is a fulfillment of circumcision.
Circumcision was given to males only because it was through the SPERM
of Abraham that the Messiah would come and it was through his blood
that the people would be sanctified. The women were included
covenantally through their males, whether the father or later their
husbands. When the Messiah had come and His blood poured out, it was
only natural for the sign to signify the one thing that is left to
happen, namely, sanctifying or cleansing or washing by the Spirit who
regenerates God’s elect, increasing their sanctification throughout
life, and persevering them until the end. Therefore, it is no
surprise that the sign of the covenant changed, nor is it surprising
that the sign went from male only to male and female. It was the
nature of the fulfillment process that brought us from Old to New
Testament. Colossians 2 in the ancient church has historically been
given as proof that Circumcision and Baptism has this relationship of
type and fulfillment, since Baptism is called the Circumcision of
Christ, or as the prophets called it, the Circumcision of the Heart.
This is no proof for the baptist position at all.
5. The reason that faith and repentance do not have to be concurrent
with baptism is because baptism signifies regeneration (Titus, “the
laver of regeneration” KJV). And just as we are passive in
regeneration, so are we passive in baptism. Baptism does not depend
upon man, nor man’s faith (just like regeneration does not depend on
man’s faith). Rather, just like regeneration, it depends on God
alone. The effect of regeneration, which baptism signifies, is faith.
Regeneration effects faith. If you believe that God has chosen your
children for salvation, then you know that they will come to believe,
and so you baptize them to compel them to that faith, this is exactly
what the saints of old did in the OT and it is exactly what God
requires of us today. You should look at your children not to
evangelize them, but to GROW and NURTURE them in the faith of their
God (because you are believing in the covenant promises). God has
given them that seed of faith, now water and grow it! What a
different disposition toward your children this is! Then you can call
them children of God, then you can call them to KEEP believing because
they MUST because of the covenant promises. No more mixed messages
for your children, they come to church and hear and sing ‘Jesus loves
me,’ but then you go home and tell them how they must believe in order
to be children of God–to become members of the church–Christ’s body!
Can you imagine if they were mature, what they would ask you?
“Daddy, how do you call me to faith when I already believe in my God;
I’ve known no other God since my birth!” It is an appropriate rebuke.”
