John, I respectfully disagree with you about what constitutes saving faith. The word for “faith” (“pistis”) as a verb is “believe” (“pisteuo”). Simply put, faith includes intellectual belief in Jesus, and infants are incapable of intellectual belief in Jesus. We can say that true, saving faith is more than intellectual belief, but it includes intellectual belief.
The most recent Southern Baptist confession of faith, the 2000 Baptist Faith and Message, defines saving faith as follows:
Faith is the acceptance of Jesus Christ and commitment of the entire personality to Him as Lord and Savior.
Some Scripture passages follow that should impact the definition of true faith:
Romans 10:9 – “That if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you shall be saved.”
Obviously, infants are incapable of understanding the resurrection. They are incapable of believing in their hearts that God raised Him from the dead. They are incapable of confessing Jesus as their Lord.
Romans 10:14 – “How then shall they call upon Him in whom they have not believed? And how shall they believe in Him whom they have not heard? And how shall they hear without a preacher?”
Infants are incapable of believing in Him. They are incapable of hearing about him from a preacher.
Hebrews 11:6 – “And without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who seek Him.”
Infants are incapable of believing that “He is,” and they are incapable of believing that He is a rewarder of those who seek Him.
James 2:17 – “Even so faith, if it has no works, is dead, being by itself.”
True, saving faith is always evidenced by good works. An unborn child or young infant is incapable of good works.
Two more relevant Scripture passages for infants:
Luke 14:33 – “So therefore, no one of you can be My disciple who does not give up all his own possessions.”
Matthew 28:19-20 – “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age.”
True disciples are willing to surrender everything to Jesus. Only true disciples should be baptized. True disciples should be taught. Infants are incapable of being willing to surrender everything to Jesus. Unborn children and young infants are incapable of learning to observe all that Jesus commanded. Unborn children are incapable of baptism, and infants should not be baptized.
