What does the Bible say about the power of God's grace?

In Psalm 21:13, we see the culmination of what Christ has accomplished for believers—praising the power of God. This power is evident in the conversion of hearts, where God transforms those who are spiritually dead into living believers. Ephesians 1:19 highlights this greatness of His power toward us who believe, showcasing that it is only through His mighty power we can have faith and be saved. This showcases God's sovereign grace that not only converts but also sustains the believer in their walk of faith.
