Human beings normally live their lives in an unbiblical manner; even Christians follow this pattern many times. The Bible commands us to love and we hate. The Bible also tells us to die to sin, but we play with it and sometimes we are burn by it.
Most people live according to their flesh (sinful nature) and are consumed by their lusts and passions. This humanistic and naturalistic orientation is what is known as a sensual life, because it is driven by our senses and emotions.
An unbeliever follows the dictates of his or her body, which in turn fills their souls with the desire to sin and to seek pleasure at all costs. The spirit of such persons is dead; therefore they can never rise above from the level of the senses and passions...unless they are saved by Jesus.
Adam and Eve were created sinless (not perfect) but when temptation appeared they forgot to live from the “inside out” and chose instead to follow the desires of the flesh. They chose to live from the “outside in” and soon afterwards, sin was IN, they were OUT and their spirit was dead.
“So when the woman saw that the tree was good for food, that it was pleasant to the eyes, and a tree desirable to make one wise, she took of its fruit and ate. She also gave to her husband with her, and he ate” (Genesis 3:6).
Adam and Eve didn’t listen to God’s warning and the world changed from a saintly paradisiacal Garden into a sinful pile of Garbage by the time of Noah (Genesis 6:5). The Bible admonishes us to stay far away from sin and the world today.
“Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the lust of the flesh, the lust of the eyes, and the pride of life—is not of the Father but is of the world” (1 John 2:15-16)
The fleshly and worldly life is not for us Christians. We must live from the inside out. The right and biblical way to live must begin in our spirit, which is in direct communication with the Holy Spirit (Romans 8:16). Our spirit then must control and direct our soul in the ways of God and our sanctified soul must move our bodies to walk in obedience and holiness before the Lord.
Adam sinned and his spirit died instantly (Genesis 2:17) and his soul began to die and eventually his physical body died as well. In Christ, our spirit was brought back to life, our soul is being sanctified and our body will one day be glorified in heaven.
This is what I call living “Inside Out” in Christ.
