The Definition of Human Nature

Bible Summary. There are many definitions of what we call human nature. Some people say that our human nature is inherently bad, a sin nature. Other people say human nature is basically good. From a Biblical perspective, our human nature is both good and bad. All of humanity has a sin nature. This is a nature that is disobedient to God. At the same time, we do have a free choice to be good or bad. God gave all humans free will. We can choose to be good. We can choose to follow the Holy Spirit. We can choose to accept Jesus as our Lord and Savior. God created humans for a purpose. God created us to be set aside for His purpose. This is also part of our humanity. See below for Biblical commentary and scriptures on the definition of human nature.

Summary Definition of Human Nature.

The short answer to the definition of human nature is it is the sum of qualities and traits shared by all humans. From a Christian perspective the definition of human nature centers around man’s free will (choice) and his relationship to God. It is our free will and our special relationship with God that makes us human.

Sin Nature.

Humans have a sin nature. A sin nature is basically a nature that is disobedient to God. We were all born with a sin nature that can be traced back through our ancestors all the way back to Adam and Eve. This tendency for us to disobey God, our sin nature, continues today in that it was passed down from our forefathers. <1–Romans 5:12–> Romans 5:12 advises us how sin has entered into all of mankind.

Romans 5:12, “Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:”

Free Will.

God gave us free will; He gave us choice. We are not just driven by our instincts or our environment. Neither are we puppets of God. We choose to be either servants of God or servants of sin and disobedience. Romans 6:16 advises us that everyone has free will.

Romans 6:16, “Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?”

The Holy Spirit In Us.

Our human nature does not need to end in corruption and death that sin brings to our lives. If we choose to follow the spirit of God, we can have eternal life and not live in sin. Galatians 6:8 advises us that we can choose the Holy Spirit over our flesh.

Galatians 6:8, “For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.”


Our human nature at it’s best is set aside for God. This is where we put God first. This is where we are willing vessels that purify ourselves to be set aside for God’s purpose (1 John 3:3, 2 Peter 1:4-7). 2nd Peter 1:6 advises us that humans can be pure and take on God’s divine nature.

2nd Peter 1:6, “And to knowledge temperance; and to temperance patience; and to patience godliness;”
