Success is about a relationship, and that relationship is with God.  And that relationship is only available through Jesus Christ.

True success can only be found in Christ.  When we look for satisfaction outside of Jesus Christ, we are looking in a place that cannot possibly satisfy us. 

Success cannot be found in religious activity, whether that religious activity is called by the name, Christianity, Secularism, Humanism, Atheism, Eastern Mysticism, or by any other name.  It cannot even be found in Bible study, as important as Bible study is.  Many have tried to study the Bible by the natural mind, as you would study a history book, and have never found a relationship with Christ.  They will run into what the Hebrews found in 2 Corinthians 3:14 and what Paul described in 1 Corinthians 2:14.
