What Is Our Nature To Sin?
We should never forget this, that it is not sinful for there to be evil thoughts in our mind. Just as it is not sinful to hear evil thoughts from an external source that can ultimately reside in our memory. These thoughts are not sins, but rather temptations. Did Jesus sin when He was tempted by the devil? No.
It is not until these evil thoughts are conceived by our own desires that they give birth to sin:
"Blessed is the man who endures temptation; for when he has been approved, he will receive the crown of life which the Lord has promised to those who love Him. Let no one say when he is tempted, “I am tempted by God”; for God cannot be tempted by evil, nor does He Himself tempt anyone. But each one is tempted when he is drawn away by his own desires and enticed. Then, when desire has conceived, it gives birth to sin; and sin, when it is full-grown, brings forth death" (James 1:12-15 NKJV).
Our sin nature is not that our flesh will never cease from sinning, as if its will has the greater authority, for our flesh cannot bring us to bondage unless the will of our spirit is weaker, in this way it permits it; but that we have the knowledge of both good and evil, and this evil knowledge resides in our members from our past experiences, constantly tempting us. We have the choice to refrain these thoughts from bearing fruit, but can anyone accomplish this without faith in the true living God?
For did not Adam and Eve both sin by eating of the fruit of the tree that was forbidden by God? Did they have a sin nature before then? Or were they both drawn by the serpents temptation being carried away by their own desires? Is it not the same case today? But what has changed since the fall is the bringing forth of the knowledge of good and evil, that has spread and resides in each and every one of us brought forth by one man, Adam.
When the Apostle Paul says, "...bringing every thought into captivity to the obedience of Christ" (2 Corinthians 10:5 NKJV), he is not saying that we should expel all evil thoughts from our mind, but to every evil thought that presents itself, to quarantine them so that the virus does not spread into our members; to not allow them to conceive and give birth to sin by our own desires.
"No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it" (1 Corinthians 10:13 NKJV).
"Truly, this only I have found:
That God made man upright,
But they have sought out many schemes" (Ecclesiastes 7:29 NKJV).
