If Justification comes through Baptisim, then:
1) Why did Jesus not baptise anyone? [John 4:2]
1. That wasn't what He was meant to do. We all know what that was.
2. Just because He didn't Baptize Himself doesn't mean we are not regerated from it. Fallacy of Appealing to Ignorance, as well as Fallacy of Hasty Generalization.
2) Why did Christ tell the criminal on the cross that he would be with him in paradise? [Luke 23:43]
The Church wasn't in existance yet. The Church was instituted by God. And Jesus told the Church to Baptize. And Baptism (actually Confirmation, but only for those Baptized at an immature age had to wait; the mature adults were Baptized, chrismed, and Confirmed all in one step) is the entrance into the Church.
3) Why is baptisim left out in many verses that explain salvation? [Romans 1:16]
Why are many witnesses called to testify in a trial? Because each has something to contribute. Each offers elements that, when pieced together, form (one hopes) the truth.
Therefore, just because many/most don't mention Baptism doesn't mean it isn't important or even vital to salvation. That's again the Fallacy of Ignorance, Fallacy of Hasty Generalization, and also Fallacy of Appealing to Masses.
4) Why did Paul say that he wasnt sent to baptise but to preach the gospel? [1 Cor. 1:17]
Because he decided that his primary mission was to preach. Also, you've misinterpreted why he didn't baptize much (and he did baptize for he was a bishop); he didn't because too many Christians at the time were not entirely understanding what baptism was; they thought baptism was in various names, but it wasn't. That is the proper context.
5) Why did Cornelius and those with him recieve the Holy Spirit before they were baptised? [Acts 10:44-48]
1. Cornelius was already a believer in Jesus
2. Just because he received the Holy Spirit didn't mean he accepted it in the orthodox fashion. Fallacy of Equivocation. Only after Baptism/Confirmation would he have accepted it with proper understanding and thus would have been truly entered into the Church.
