(1 Peter 3:15-16): ...The Voice (VOICE)
15-16 but exalt Him as Lord in your heart. Always be ready to offer a defense, humbly and respectfully, when someone asks why you live in hope. Keep your conscience clear so that those who ridicule your good conduct in the Anointed and say bad things about you will be put to shame.
So, we are to be gentle and respectful to even our enemies, as it is, we live with Christ's demeanor in us, as well as a mind placed in Him. This tells us that if a man or woman lives in God's light, (and not the light of a humans godliness) the clear nature of things will be as clear and bright as light itself. If a man is under God's light, he will discern the intrinsic nature of things. The only time a person genuinely knows (even) himself is when he knows himself under God's light. If we are not in God's light, we may sin, in responding to another labelled under the "Work for Christ" but not feel the evil of sin. We may fail the Lord, living in the flesh serving others morally, but we will not feel the shame of failure. We can perform well outwardly, but inwardly we will not know how deceitful we are. We may be humble outwardly, but inwardly we will not know how proud we are. We may appear gentle outwardly, but inwardly we will not know how stubborn we are. We may appear spiritual outwardly, but inwardly we will not know how fleshly we are. When God's light shines on us, our true condition will be exposed, and we will see and admit how blind we have been. Now keep in mind I speak of God's worker here, as well as God's newly born.
The difference between the Old Testament and the NT is that the OT shows men what is right and what is wrong thru outward laws, while the NT shows men the true nature of things thru the Holy Spirit dwelling within. We often see our error thru doctrines, but we do not see our error thru God's light.
We have to realize that it is superficial to see our errors in the way we think, speak, and act, behaviorally with others thru doctrines - set aside from the Holy Spirit now in living a (Spiritual/spiritual) resurrected life. Only when we see our errors thru God's light is there a thorough seeing. But to answer the question, the good news is when we are in God's light we see what God sees. This is seeing the light in the light, and as God transforms us and employs our will in our acts of faith, He develops our demeanor to follow His own by His power and grace of gentleness and respect.
