Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: 1 Peter 5:8
While Satan is constantly looking for openings, for breaches in our armour,
God is fighting for us, helping us to be aware of and giving us wisdom
from His word on how seal up any openings we might have.
Good and Evil is a constant battle.
If we store iniquity in our heart, we are letting the enemy use us.
That iniquity will spill out and do harm.
Lest Satan should get an advantage of us:
for we are not ignorant of his devices. 2 Corinthians 2:11
The verse right before it is reminding us not to be unforgiving.
That is just one of Satan’s many openings that could snare us in battle.
Fear God and keep your sins cleansed and remain pure before the Lord.
Who shall ascend onto the hill of the Lord?
Or who shall stand in His Holy Place?
He that hath clean hands and a pure heart,
who hath not lifted up his soul unto vanity, nor sworn deceitfully.
He shall receive the blessing from the Lord,
and righteousness from the God of his salvation.
Such is the generation of them that seek Him, that seek Thy face,
O God of Jacob. Selah Psalm 24:3-6
