"In mercy and truth atonement is provided for iniquity; And by the fear of the Lord one departs from evil" (Proverbs 16:6).
One would be hard-pressed to find a more concise description of God's part and man's part in salvation "by grace...through faith" (unless it is this quote from Ephesians 2:8-9). God provides atonement for our sins out of the abundance of His mercy, revealing it by His word of truth. As the apostle Paul noted, "But when the kindness and the love of God our Savior toward man appeared, not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit" (Titus 3:4-5). God's kind love and generous gift of mercy saves us.
Yet, without the faith that comes from "the fear of the Lord," one will not depart from evil to be saved. As Peter said, "In truth I perceive that God shows no partiality. But in every nation whoever fears Him and works righteousness is accepted by Him" (Acts 10:34-35).
Without God's mercy we could not be saved. Without God's truth we would not know we were lost in sin, and we could not have faith to fear Him and work that righteousness that He accepts. Truly, in God's salvation "Mercy and truth have met together; righteousness and peace have kissed" (Psa. 85:10). God's mercy is offered to you. His truth commands you to believe and do His will. If you will fear the Lord and obey His gospel in faith, you will receive atonement for your sins (read Acts 2:36-41).
