'Away' in the Bible

On the other hand, I am writing a new commandment to you, which is true and realized in Christ and in you, because the darkness [of moral blindness] is clearing away and the true Light [the revelation of God in Christ] is already shining.

The world is passing away, and with it its lusts [the shameful pursuits and ungodly longings]; but the one who does the will of God and carries out His purposes lives forever.

You know that He appeared [in visible form as a man] in order to take away sins; and in Him there is [absolutely] no sin [for He has neither the sin nature nor has He committed sin or acts worthy of blame].
