Man was directly and immediately created by God in His image and likeness. Man was created free of sin with a rational nature, intelligence, free-will, self-determination, and moral responsibility to God (Genesis 2:7, 15-25; James 3:9).
God's intention in the creation of man was that man should glorify God, enjoy God's fellowship, live his life in the will of God, and by this accomplish God's purpose for man in the world (Isaiah 43:7; Colossians 1:16; Revelation 4:11).
In Adam's sin of disobedience to the revealed will and Word of God, man lost his innocence, incurred the penalty of spiritual and physical death, became subject to the wrath of God, and became inherently corrupt and incapable of choosing or doing that which is acceptable to God apart from His divine grace. With no powers to enable him to recover himself, man is hopelessly lost. Man's salvation is thereby wholly of God's grace through the redemptive work of our Lord Jesus Christ (Genesis 2:16-17; 3:1-19; John 3:36; Romans 3:23; 6:23; 1 Corinthians 2:14; Ephesians 2:1-3; 1 Timothy 2:13-14; 1 John 1:8).
Because all men (people) were in Adam, a nature corrupted by Adam's sin has been transmitted to all men of all ages, Jesus Christ being the only exception. All men are thus sinners by nature, by choice, and by divine declaration (Psalm 14:1-3; Jeremiah 17:9; Romans 3:9-18, 23; 5:10-12).
