God requires at this time just what He required of the holy pair in Eden–perfect obedience to His requirements. His law remains the same in all ages. The great standard of righteousness presented in the Old Testament is not lowered in the New. It is not the work of the gospel to weaken the claims of God’s holy law but to bring men up where they can keep its precepts.
The faith in Christ that saves the soul is not what it is represented to be by many. “Believe, believe,” is their cry; “only believe in Christ, and you will be saved. It is all you have to do.” While true faith trusts wholly in Christ for salvation, it will lead to perfect conformity to the law of God. Faith is manifested by works. And the apostle John declares, “He that saith, I know Him, and keepeth not His commandments, is a liar, and the truth is not in him” (1 John 2:4).
It is unsafe to trust to feelings or impressions; these are unreliable guides. God’s law is the only correct standard of holiness. It is by this law that character is to be judged. If an inquirer after salvation were to ask, “What shall I do to inherit eternal life?” the modern teachers of sanctification would answer, “Only believe that Jesus saves you.” But when Christ was asked this question He said, “What is written in the law? how readest thou?” And when the questioner replied, “Thou shalt love the Lord thy God with all thy heart, . . . and thy neighbour as thyself,” Jesus said, “Thou hast answered right: this do, and thou shalt live” (Luke 10:25-29).
True sanctification will be evidenced by a conscientious regard for all the commandments of God, by a careful improvement of every talent, by a circumspect conversation, by revealing in every act the meekness of Christ.
