Faith=Obedience... go together?

In Proverbs 4:23, "Above all else, guard your heart, for it affects everything you do." (NLT) In Proverbs 21:2, "People may think they are doing what is right, but the Lord examines the heart." (NLT) "David son of Jesse is a man after my own heart, for he will do everything I want him to do." Acts 13:22 & 1 Samuel 13:14 (NLT) Matthew 22:36-38 (New International Version) "Teacher, which is the greatest commandment in the Law?" Jesus replied: " 'Love the Lord your God with all your heart and with all your soul and with all your mind.'This is the first and greatest commandment. My question is this: Can a Christian be forgiven when he/she do not obey God's commands? Faith itself is not in my works. My faith is the generator of my works which is obedience. Faith produces obedience (works). Faith in God is being is expressed in doing which is obedience. God's letters are written in my heart to be known and read by everybody. Written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of my heart (2 Corinthians 3:2-3). My life as a Christian takes work and requires the commitment of my heart, mind and body. Christ is not outside of me but He is inside me. Since Christ is within me, I must listen to His Word and walk in His steps (2 Corinthians 4:10).

Quote Jesus said: Luke 14:26-27 (NIV) "If anyone comes to me and does not hate his father and mother, his wife and children, his brothers and sisters—yes, even his own life—he cannot be my disciple. And anyone who does not carry his cross and follow me cannot be my disciple."
