In 2 Corinthians 5:17 (NASB), the Apostle Paul proclaims that “if any man is in Christ he is a new creature; the old things passed away; behold new things have come.”
This means that when a person asks Jesus Christ to become their personal Savior and spiritually applies His sacrificial atonement on the cross to their lives, then a process of transformation begins that will take them out of the spiritual and moral darkness of their old behavior patterns which broke God’s laws and bring them into a new lifestyle which lives according to God’s principles of living found in the Bible.
While for some people this transformation process could be comparatively easy, yet for some other people the transformation process will take a lot of work between the new Christian and the indwelling Holy Spirit in order to get rid of the old worldly behavior patterns and then replace them with new behavior patterns that are based on God’s principles.
As new Christians daily read the Bible to learn God’s principles, talk to God in prayer about their problems, and use the power of the Holy Spirit to be able to live according to God’s principles; that transformation process will take place and new Christians can develop a close relationship with God.
An important lesson for new Christians to learn is found in Matthew 24-25, where Jesus tells His followers to build the spiritual house of their lives on the rock of His teachings so that when the storms of life’s problems, the storms of various temptations that will distract them from following God’s principles, and the strong winds of people’s criticisms for living according to God’s principles will blow hard against their house in order to try and tear it apart; their house will be strong enough to withstand those storms because it has such a good foundation (and Christians are using the power of the Holy Spirit to hold it together).
It is also important for new Christians to find a good Christian Church that believes that the Bible is the word of God, has some messages that come from the Bible, has some good times of worshipping God, and has some good support groups that can help new Christians overcome the many problems that Christians have as they are living in our modern society.
The more that new Christians do the above things, the more they will grow in their Christian faith, the more they will become beautiful members of God’s spiritual kingdom of light, and the more that they will become great beacons of the light of God’s spiritual kingdom that brightly shines in the midst of the many forms of darkness in our modern society. As Christians do that some people who are living in darkness may become attracted to that light and follow it all the way to asking Jesus to become their personal Savior and becoming beautiful members of God’s spiritual kingdom of light.
