When in darkness, we cannot see. If we want to be able to see in darkness, it's simple; we need light. We can refer back to 1 John 1:5-7 – "This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all. If we say that we have fellowship with Him, and walk in darkness, we lie and do not practice the truth. But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin." – Jesus opens our eyes to see the truth. To see and believe that we are saved from our sins. Christ opened a man's eyes so that he can see, let us pray that He likewise, opens our eyes to the truth.
