It's only if we require an immediate and spontaneous baptism that sprinkling begins to be entertained, but even that is not a necessity, as argued above.
Why entertain anything with respect to the mode? Immersionists and anti-immersionists are falling into the trap of making Scripture speak to an issue it nowhere addresses. If mode wasn't important in either the didactic or historic portions of the NT, why should it consume our time and energy? The irony here is that we all agree on the practice of taking a little bread and wine in the Lord's supper without requiring a full meal for each participant. We recognise it is the element that is important, not the amount of it. There is no reason why the same can't apply to baptism.
