What makes a true Christian?

There are many facets to the answer of this question. I believe what makes a true Christian is their devotion,obedience,and belief. Consider the martyrs of the faith and the disciples,and of course our ultimate example,Jesus. The freedom we will experience through Christs atoning sacrifice comes to us with a battle and a commision. Often we expect all the blessings and the ability to skip from mountain top experience to mountain top experience,and don't realize the valleys and the losses we must also endure. Being a Christian does not mean we have a "free pass" through life. We must still face the difficulties of the world. But in those struggles,in that battle, we have God to give us hope. What must characterize a true Christian is there devotion to desiring the will of their Father and not of their own,understanding that all things happen for a reason,God's reason. Also their obedience to that will,the guidance of His Almighty gracious hands leading us on,especially when that means they must give up comfort and normality. They have to be considerably different(In the world but not of it). Christians must believe in God's Word,not just a part,but the whole of the Truth.
