A person’s inability to be holy and pure is not then liberty to sin because of grace. Just because you cannot escape the flesh and stop sinning, which is impossible, you do not give up trying to please God through obedience, and chose the default into laziness and wanton desire while assuming the abundance of grace given in Christ.
How grievous, how sad.
Rather, lean into the Spirit, squeeze yourself into His indwelling presence, and how then can you want to intentionally sin, for such sorrow will overwhelm you, as a necessary result from the displeasure you are causing your loving Father, who has with astonishing lovingkindness, adopted you into Himself.
“This is the judgment that the Light has come into the world, and men loved the darkness rather than the Light, for their deeds were evil. For everyone who does evil hates the Light, and does not come to the Light for fear that his deeds will be exposed. But he who practices the truth comes to the Light, so that his deeds may be manifested as having been wrought in God.”
