…who also made us adequate as servants of a new covenant, not of the letter but of the Spirit… 2 Cor. 3:6
When you go for a preventive care checkup, the doctor will make you take some lab tests to know if there are any health issues. The doctor will provide the diagnosis based on the reports and recommend a treatment. The reports cannot provide a solution, they will only point out the problem. It is the doctor who treats the patient.
In the same way, the law of the old covenant makes us realize our sin, but it cannot wipe it away. Only by believing in the Lord Jesus Christ can we have forgiveness for our sins. The law (Ten Commandments) still points out sin and shows us how to obey God, but forgiveness comes only through the grace and mercy of Christ.
It is the Holy Spirit who gives NEW life to all who believe!!
