Pro 28:1 Guilty criminals experience paranoia even though no one threatens them. But the innocent lovers of God, because of righteousness, will have the boldness of a young, ferocious lion! (TPT).
Absolute righteousness is the basis of total boldness. If there is just a chink in that armour the heart loses its bold confession. That’s why our righteousness is on Jesus. In Him, we have absolute righteousness which gives us absolute boldness in this world.
2Co 3:12 So then, with this amazing hope living in us, we step out in freedom and boldness to speak the truth.
Let your heart rest in the perfect righteousness of Jesus. Then boldness rises.
The devil is an accuser and uses just about anything to accuse believers
