John 7:24 English Standard Version (ESV) Do not judge by appearances, but judge with right judgment.”
I have always seen things in black and white. That is just part of who I am as a natural born, born in the flesh. When I became born again, that part of my natural born personality became enhanced and reinforce by the Holy Spirit.
Being born to know what is right does not make us able to do right. Being able to do right comes from righteousness which is not a natural born trait. It is however part and parcel to being born in the Spirit. The Holy Spirit, who is the third person of God, He is Holy and Righteous. He is the source of right judgment.
What is lacking in natural born judgment is how righteousness approaches truth. He sees beyond the obvious. In the natural born we see nothing but violations in our black and white world. There is no mercy or grace that emanates from a world that is either black or white, right or wrong.
Matthew 9:13 English Standard Version (ESV) Go and learn what this means: ‘I desire mercy, and not sacrifice.’ For I came not to call the righteous, but sinners.”
Seeing who needs salvation does not teach you how to bring them salvation. Jesus did that by living God’s perfect love as the example. We did not walk in righteousness just because we knew right from wrong. Paul addressed those difficult issues in Romans 7. He finished that chapter by acknowledging Jesus Christ as being the answer to the problem.
In the very next chapter Paul begins with therefor there is no condemnation. Knowing the truth in black and white does not give us the right to condemn. We cannot walk by faith without Christ nor can we exercise right judgment without Him who is righteous.
