I am not attacking Christianity. I am simply stating that their are others out there who do not believe what you believe and it is important to understand what they actually believe.
Seeing the world from your own narrow perspective is exactly how the Muslims see the world and their view is wrong.
Whenever we focus, we narrow our perspective. By focusing on God through faith in Christ, we are in a position where He is able to clarify our perception by Divine standards. Seeing God through faith in Christ allows God to further our understanding. Narrow perspective isn't wrong, but if one narrows their perspective by focusing on anything other than through what God has provided for that perspective, then we blur Him altogether.
The Greek word "PISTIS" is translated as faith and as belief in several important passages in Scripture. There are true beliefs and false beliefs. That which is trustworthy is also described by the adjective of PISTIS.
Our sanctification begins with faith and continues with faith through Him.
It is more important to remain in faith through Him and understand His faith, that belief, than it is to understand the faith or belief of all others.
The same faith or belief is available to Muslims if they choose with their individual volition to accept Him. One proviso might be noted, though, that while I may say the same faith is available to them, until they think along those lines, they might not get to the point of hearing His Word because it has been outlawed in many of their lands. So in a sense, it might be more accurate to say faith isn't as available to them as it is in lands where we are free to read and study Scripture.
This makes it all the more imperative to spread the good news of Christ to each and every Muslim at every opportunity, not to water it down, worrying about it not being received. This doesn't mean we are to be offensive to those who seek Him, but there is a a discernible difference between being perceived as offensive to a believer and being offensive to an antichristian spirit. Those who are enemies of Christ will claim offense by any communication or thinking about Him.
Our task is merely the Great Commission. The tasks of salvation are purely the work of God. Whether or not they accept Him through faith in Christ is their business, not mine, but we are commissioned to communicate that Gospel to them.
