We know we are saved by faith through the revelation of God's grace and our personal acceptance of Christ's lordship, as stated in Romans 10:9.
The assurance of salvation comes from understanding that faith is a gift from God and involves both knowledge and belief. Romans 10:9 states that if we confess with our mouths and believe in our hearts that Jesus is Lord and that God raised Him from the dead, we will be saved. This indicates a clear condition that must be met, yet it is undergirded by God's sovereign grace, which enables us to fulfill these requirements. Paul teaches that it is God who works in us to will and to act according to His purpose, ensuring that genuine faith always leads to genuine belief, thus confirming our salvation not by feelings but by the objective truth of God's Word.
