There is the first love in the faith in God. When you firsthand experience works of the Holy Spirit after accepting Jesus Christ, you attend the service with the thanksgiving for the grace of God and take delight in living by the word of God. But if your love becomes cold with the passing of time, you will lead a religious life from the sense of duty or hypocritically. On the contrary, if you are always awake and abide in the word of truth, your first love for the Lord will improve day by day and live a happy religious life all the time.
