God created us to have a relationship with him, but sin separates us from God. We all sin, but his Son, Jesus, is the the only one who can forgive us of our sins and restore our relationship with God.  The Bible teaches us this truth.  
God, indeed, makes all things new. 
     "I have hidden your word in my heart, that I might not sin against you."  Psalm 119:11 (NLT)
