Because as Christians we are slaves of righteousness, obeying the law of God must be the joy of our heart.
Christians are not merely slaves of righteousness, we are also sons and daughters in the family of God.
The apostle Paul explains how slavery to sin never produces any benefits. Instead, it only leads to eternal death.
For Christians, eternal life is a present reality that won’t be fully consummated until this life ends or Christ returns.
The moment your body stops functioning you will awaken in one of two eternal destinations: heaven or hell. It is absolutely critical to know which of those destinations will be a reality for you.
The consequence of your sin is eternal punishment, but the free gift of God in Jesus Christ is eternal life. If you repent of your sins and believe upon the Lord Jesus Christ you will be saved from eternal punishment.
