If man is incapable of pleasing God in his sins, then why does God commend Cornelius in Acts 10?

How do the commending statements about Cornelius harmonize with teaching regarding human depravity?

Cornelius was just and reputable, prayed, feared God, and gave alms (Acts 10:2, 4, 22, 24, 31, 35). These notable commendations coordinate with Peters growing awareness ("I perceive," verse 34) through previous revelation (eg. Luke 24:47), his vision (Acts 10:11-16), and his circumstances (verses 19-33) that God makes no distinction between Jews and Gentiles who seek Him (verse 35).

"There is not a just man upon earth" (Ecclesiastes 7:20; Romans 3:10); "there is no fear of God" in man by nature (Romans 3:18); "there is none that seeketh after God" (Romans 3:11). These harmonize with what is said about Cornelius only because he responded to the light of divine revelation and the dealings of the Spirit of God. Although he was not saved (Acts 11:14), he chose to do right things; yet each of those acts came short of Gods righteous requirements (Romans 3:23). None of what is said about Cornelius indicates that he was saved apart from grace through faith (Ephesians 2:8). Gods grace spoke to Cornelius, granting him repentance (11:18) and remission of sins (10:43). Before and after his salvation, Cornelius had nothing in which to boast before God. As is proper, he submitted to God.
