According to one poster on here, christians can be both Light and darkness. But this ideology...and that's exactly what it is...an ideology...is that Christians can be both darkness and Light. Well, let us delve into God's holy writ and see what He has revealed to us concerning the matter. Jesus said Believe in the light while you have the light, so that you may become children of light.”[John 12:36] Here we can see Jesus is speaking to His disciples about the Light. We know He is the Light as He said "I have come into the world as a light, so that no one who believes in me should stay in darkness."[John 12:46] True believers are no longer in the darkness, but have come to the Light, this Light being Christ. Then there are other sayings of His such as “I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.”[John 8:12] Jesus also said in John 11 that those who walk in the light(daytime) don't stumble, seeing they can see. It is those who are in darkness who stumble and fall, seeing they have no light to see where they are going. Even the Psalmist said Your word is a lamp for my feet, a light on my path.[Psalm 119:105] So those who are God's do not reside in darkness by bask in His Light. Apostle Paul proclaimed this to King Agrippa “ ‘I am Jesus, whom you are persecuting,’ the Lord replied. ‘Now get up and stand on your feet. I have appeared to you to appoint you as a servant and as a witness of what you have seen and will see of me. I will rescue you from your own people and from the Gentiles. I am sending you to them to open their eyes and turn them from darkness to light, and from the power of Satan to God, so that they may receive forgiveness of sins and a place among those who are sanctified by faith in me.’"[Acts 26:15-18] Apostle Paul was sent by God to proclaim His gospel, a message so powerful that God is able to use it to transfer those from the kingdom of darkness(where Satan rules, though God has limited his authority to the goats only...I.E...the world...the lost...) to the kingdom of Light(where God reigns supreme)[Colossians 1:13]. So dear readers, do not be deceived by those who say true saved peoples can dwell in darkness. We now live in the kingdom of the Son whom God the Father loves, Christ.
