Let the profundity of these deceptively simple words sink deep into your souls. There is no such thing as secret sin. The path you took to get to her door, the thoughts you contemplated on the way, the plan of the sin itself and even the imagining of how you would deal with the aftermath are not one whit hidden from His view. What you do, you do as though you had asked Him to accompany you in the way. Beloved, we must ever be mindful that every thought, every action, every motive, every word - all are altogether comprehended by Him at all times.
Nothing is hidden.
