It's so obvious, I can't believe how many people overlook the healing of the paralytic in Matthew. The palsied man cannot speak for himself, cannot make his wishes known directly to Jesus. Thus: "And Jesus, seeing
their faith," healed the man.
So, I'm not really sure where it says in the Bible that without exception Christ MUST be chosen by anyone of us, when it clearly demonstrates here that the faith of this man's neighbors was reason enough to bring him healing and forgiveness of sins, since he - like an unbaptized baby - could not speak for himself.
Also, if as you say "Christ must be chosen by you, not for you", what happens to the mentally retarded, the autistic, the insane, who can neither reason the Gospel, nor make known their acceptance of Christ? Since they can't make that "commitment", are they excluded from salvation?
Those who are incapable of understanding what it means to be saved will be saved by Christ's understanding and love. Ignorance cannot be used as an excuse for those who are capable. For those people who live in countries that receiving the word is near to impossible I believe he will apply the same level of understanding and reason.
What irritates me are people who think baptizing an infant automatically "save" them for the remainder of their years. Clearly if someone had baptized Jeffry Dalmer and he didn't actually accepted the faith he would not be saved.
When I was baptized I professed my belief in Jesus as my savior in front of a congregation. The congregation recognized that it was my desire to accept Christ and to witness for him before all.
I believe baptizing a child is more for the parents than for the child. Basically it's a statement of the parents that they will raise their child in the light of God and teach their child what it means to be faithful. When the child reaches maturity they must decide if they accept the faith.
