Generally speaking, the “social gospel” seeks to apply Christian ethics to social problems such as poverty, slums, education, alcoholism, crime, and war. It’s a great idea! The problem is; these things are emphasized while the doctrines of sin, salvation, heaven and hell, and the future kingdom of God are often downplayed.
From God’s perspective; man can never be saved or transformed by social justice. He can only be saved and transformed by personal repentance and faith in Christ.
Instead of a social gospel, Jesus preached the saving power of faith in His sacrifice on the cross for our sins and the transforming work of the Holy Spirit in our lives.
Why? Because according to the bible –
The entire nature of man, mentally, morally, spiritually and physically is sadly affected by sin.
The understanding is darkened (Eph. 4:18; 1 Cor. 2:14); the heart is deceitful and wicked (Jer. 17:9,10); the mind and conscience are defiled (Gen. 6:5; Titus 1:15); the flesh and spirit are defiled (2 Cor. 7:5); the will is enfeebled (Romans 7:18); and we are utterly destitute of any Godlike qualities which meet the requirements of God’s holiness (Romans 7:18).
This does not mean the entire absence of conscience (John 8:9); nor of all moral qualities (Mark 10:21); nor that men are prone to every kind of sin.
It does mean, however, that man is totally destitute of love to God which is the all absorbing commandment of the law (John 5:42); that the natural man has an aversion to God (Romans 8:7); and that man is in possession of a nature that is constantly on the downgrade, and from the dominion of which he is totally unable to free himself (Romans 7:18,23). (From The Great Doctrines of the Bible by William Evans.)
As the Scriptures say, “No one is righteous—not even one.” (Rom. 3:10, NLT) For everyone has sinned; we all fall short of God’s glorious standard. (Rom. 3:23, NLT)
