“I am come a light into the world, that whosoever believeth on Me should not abide in darkness.” -John 12:46
This world is dark as midnight; Jesus has come that by faith we may have light and may no longer sit in the gloom which covers all the rest of mankind.
Whosoever is a very wide term: it means you and me. If we trust in Jesus we shall no more sit in the dark shadow of death but shall enter into the warm light of a day which shall never end. Why do we not come out into the light at once?
A cloud may sometimes hover over us, but we shall not abide in darkness if we believe in Jesus. He has come to give us broad daylight. Shall He come in vain.’ If we have faith we have the privilege of sunlight: let us enjoy it. From the night of natural depravity, of ignorance, of doubt, of despair, of sin, of dread, Jesus has come to set us free; and all believers shall know that He no more comes in vain than the sun rises and fails to scatter his heat and light.
Shake off thy depression, dear brother. Abide not in the dark, but abide in the light. In Jesus is thy hope, thy joy, thy heaven, Look to Him, to Him only, and thou shalt rejoice as the birds rejoice at sunrise and as the angels rejoice before the throne.
