We know we are saved by God's grace through faith in Jesus Christ, which is evidenced by our love for Him and our obedience to His commandments.
The assurance of being saved by grace comes from a true understanding of justification, which is being declared righteous before God based on the merits of Christ alone. This is articulated in passages such as Romans 4:5, which states that faith in Jesus, not our works, justifies us before God. Our love for Christ and the resulting obedience are evidences of our faith and the inner transformation by the Holy Spirit. We must fix our eyes on Christ, as the source of our salvation and righteousness, rather than our performance. This understanding provides the believer with the confidence of their standing in grace, as we see in Ephesians 2:8-9.
