Humanity rapidly degenerates because of the inherent, sinful nature people have. Just a few generations after Adam and Eve sinned, there was widespread iniquity (Gen 6:5-7). Society today continues that downward slide, away from God’s holy standards.
When people turn their backs on God, “suppressing the truth with wickedness”, He gives them over to a depraved mind and they do whatever they want without their conscience intervening. Instead they reject what is good and live to satisfy their flesh (Rom 1:18-28; 2 Tim 3:8). Such people are full of corruption, unfit for doing anything good, they are morally worthless (Tit 1:15,16).
By not making use of the opportunities given them a person is just like barren land that only produces weeds and is considered useless (Heb 6:8). In ‘the last days’ people will lack sound principles, besides loving themselves and pleasure more than loving God, because Satan’s influence is paramount in those who are disobedient (Ex 20:3; Lk 10:27,28; Eph 2:2; 2 Tim 3:1-5).
