Walk in the Light and be free

John 1:7. . .”But if we [really] are living and walking in the Light, as He [Himself] is in the Light, we have [true, unbroken] fellowship with one another, and the blood of Jesus Christ His Son cleanses (removes) us from all sin and guilt [keeps us cleansed from sin in all its forms and manifestations].”
Even though salvation is a free gift, it is not cheap and we need to make sure that we indeed to belong to the Lord. The bible says to believe on the Lord Jesus Christ and you will be saved (Acts 16:31).

Billy Graham said once a christian is one who believes on Jesus as Lord & Saviour and commits their life to following Him. Even though salvation is not based on works, if we do not have good works in our life then we need to question if we really know the Lord.

Jesus did say in one of the gospels that we will know each other by our fruit and that not everybody who calls Him Lord will enter His kingdom-only those who have truly repented of their sins and have a intimate personal relationship with Him (Matt. 7).
