In the midst of the intense fog of demonic deceptions and the many forms of spiritual, moral, and intellectual darkness that affects many people in many parts of the world there is the brightly shining beacon of the proclamations of Jesus Christ that:
“I am the light of the world; he who follows Me shall not walk in the darkness, but shall have the light of life. (John 8:12 NASB)
I am the way, the truth, and the life; no one comes to the Father, but through Me.” (John 14:6)
In these verses Jesus is declaring that He and His teachings were the true spiritual light and so those people who followed that light into accepting Jesus as their personal Savior would be brought out of their spiritual darkness and brought into God’s spiritual kingdom of light.
Jesus could make such a declaration because He completed God’s plan for the spiritual redemption of mankind when He died on the cross taking the punishment of death that everyone who broke God’s laws deserved.
As a result of Jesus completing God’s redemptive plan, those people who ask God to forgive them for breaking God’s laws, accept Jesus Christ as their personal Savior, and then spiritually apply His sacrificial atonement on the cross to their lives will be forgiven by God for breaking his laws, have the spiritual death sentence they deserved for breaking His laws removed, brought out of the spiritual kingdom of darkness and brought into God’s spiritual kingdom of light, made God’s newly restored creation, and be sent the insight and power of the Holy Spirit to live inside of them to give them the ability to live according to God’s principles of living found in the Bible
As Christians daily read the Bible to learn God’s principles, use the power of the indwelling Holy Spirit to live according to those principles, and talk to God in prayer about their problems; they can develop a close relationship with God that will help them overcome the problems that they will face during the rest of their journey of life.
The more Christians do those things, the more they will shine the light of God’s kingdom for people to follow so they can come out of their darkness into God’s spiritual kingdom of light.
