'Plainly' in the Bible

for the invisible things of Him from the creation of the world, by the things made being understood, are plainly seen, both His eternal power and Godhead -- to their being inexcusable;

Did that which is good [the Law], then become death to me? Certainly not! But sin, in order that it might be revealed as sin, was producing death in me by [using] this good thing [as a weapon], so that through the commandment sin would become exceedingly sinful.
