1 John 3:23,24 - God commands us to believe in Jesus; we must keep His commands to abide in Him. If we recognize the importance of faith, we must recognize the importance of obedience, since faith itself is a command from God that we must obey.
John 6:28,29 - People asked what they must do to work the works of God [cf. 1 Cor. 15:58; 16:10]. Jesus said the work for them to do is to believe. [Acts 16:30f]
Faith is essential to salvation. But faith is a command - a work - something required in obedience to God. Therefore, obedience is essential to salvation, for here is another act of obedience that is required for salvation. If someone claims that works of obedience are not necessary, he is (unintentionally) saying that faith is not necessary. If he then says faith is necessary, he contradicts himself.
