Meaning comes through a personal and growing relationship with Jesus Christ as Lord and Savior of our life. Jesus is not just a savior, He is "The Savior of the world" and we must embrace Him as our personal Savior.
The world teaches that all religions lead to God and eternity, but that is not what Jesus taught.  Jesus said that He is "the way, the truth and the life, and that no one could come to the Father except through Him." Jesus came to earth to pay the penalty for our sins and to forgive us of our sins.  Through Jesus a bridge is built back to our Heavenly father. Through Jesus a broken relationship with God is re-established.  
Man lives apart from God by his sins, but if we ask God's forgiveness and invite Christ to be our savior, He comes into our life and gives us everything we need to find happiness and peace. When Christ comes into our life, we immediately get a sense of meaning that was not there before.  He makes life worth living.  He promises to be with us and help us everyday of our life.  A life with Jesus Christ as our personal savior is one filled with great meaning.
