Let's take them one at a time, primarily to look for any mention of infant baptism.
First of all, he is speaking to adults only. Secondly, do you know of any way an infant can repent?
Luther used this passage, but there is no mention of baptism. When the children came to him, he did not baptize them.
Again, no mention of baptism, and not even a mention of salvation. Might also note that he says a person must accept the Kingdom "like a little child", not "as a child".
This is absolutely terrible. Baptism has replaced circumcision? That is never stated in that passage. This is so bad that it borders on intentional deceit. I can say that since I know you did not write this. Rather amazingly, I think, you copied it from a Catholic website.

Here is the passage. See for yourself. "In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, 12 having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead." And again, there is no mention of infant baptism.
Yes, people got baptized, but there is no mention of infants being baptized.
In fact, you can read the entire NT and not find a single instance of an infant being baptized, and nor can you find a single occasion where a person professed to have become a Christian as an infant. Might also ask this. When did they get baptized? Was it not after a confession of faith in Jesus? Pretty sure you did not do that as an infant.
