In this Scripture, Christ was drawing a parallel between the time of His coming versus the time of Noah and the flood--and there certainly was nothing secret about the flood!
Sa talatang ito, inilalarawan ni Cristo ang pagkakatulad ng panahon ng Kaniyang pagdating sa panahon ni Noe at ng baha - at doo'y tiyak na walang lihim o secreto tungkol sa baha!
