Of course this is just based on these 6 words & without examining the contexts believe, faith, & faithful appear in, but still this should get us thinking. Our Father is more concerned with having a relationship of trust with His children than with having obedient servants.
We are however called to be obedient children (1 Peter 1:14), but obedient to the highest command of God which is "Trust in Me" (1 John 3:23, John 14:1). Trusting is obedience & trusting results in further obedience. The bible clearly communicates trust as most important. The difference between trust & obedience should be recognized. Therefore trust must come first. Trust has to be more important because everything is wrapped in trust. Many attempt to obey without trust. You can obey (ideas of God, the law, traditions of men, self-professed human leaders) without trusting God but you cannot trust God without obeying Him. Start with trust & you will have everything. Start with obedience & you may never get to trust.
