Nicodemus would probably be welcome at any church today. He seems an ideal member—principled, knowledgeable, and courteous. And as a Pharisee, he followed strict Jewish rules, which certainly made him religious. However, Nicodemus had serious drawbacks: He was blind to the truth and spiritually lost. In other words, he didn’t have a relationship with Jesus.
When Nicodemus came to see the Lord in John 3, Jesus explained to him that no amount of goodness could erase or change a person’s nature. Instead, everyone who desires to serve God must be born again. Jesus promised that if Nicodemus trusted Him as Savior, then he would enter into a brand-new life. His old flesh nature would be replaced so that he could have a real relationship with God—instead of appearing to be a religious man, Nicodemus would be a true believer.
No one gets into heaven because of good works and kind behavior. At the end of our earthly life when we stand before God, only our relationship with Him will matter. We will want to show Him that in place of our old sinful nature, we now have the living Spirit we received when Jesus Christ came into our life.
