We are saved by trusting Jesus for the forgiveness of sin; we are blessed and rewarded by obedience to the Ten Commandments. Our salvation depends on simple faith in the blood of Christ, while our rewards in heaven depend upon our willingness to be obedient to God in all things. Without the law there is no need for a gospel, and without the gospel there is no genuine obedience to the law.
But mark my words: There is no holiness apart from the assurance of salvation in the atoning blood of Jesus Christ.
“For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God—not by works, so that no one can boast. For we are God’s handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do.” Ephesians 2: 8-10
