Jack-
If humans have as much instinct as animals then why do we need directions?
Birds and butterflies migrate without maps but instinct.
Conscience and emotions are also two different things.
True, self preservation is a great motivator, and as Paul wrote for when the people of nations do not have the law, they do by nature the things contained in the law....not having law they are a law unto themselves....Romans 2vs14,15,
If logical deduction was all that was necessary, then why don't we have world peace?
Isn't having peace on earth a logical deduction to desire ?
So isn't it a logical deduction that a person is basically as good or evil as he so chooses?
Inevitably the more a person allows or permits himself to be influenced by the world's bad spirit the more he becomes to have a bad spirit choosing to be more like Satan's selfish qualities. So, since we have high-order brain function we choose what will govern our lives. Either choose being governed by God's spirit or ensnared by the world's unholy spirit which is manifest by the behaviors and actions described at 2nd Tim 3vs1-5,13.
1st Peter 5v8 says to be alert! because our enemy the devil walks about like a roaring Lion seeking to devour us. But Satan is not stronger in a spiritual sense because as 2nd Peter 2v9 mentions that God knows how to deliver righteous people out of temptation.
We can not be tempted beyond what we can bear. God makes the way out.
-1Cor 10v13
Satan does not succeed in destroying the sheep-like ones of Matthew chapter 25.
Those humble, mild, meek sheep-like people are preserved alive and saved right into the start of Jesus 1000-year reign over earth having the prospect of everlasting life in view as originally offer to Adam to live forever on a paradisaic earth.
