Claiming the faith of Abraham is what they might profess, when in fact that is a lie, it is the heritage of lineage they're referencing. Further the God they serve and the God of the Bible are not the same. Ask a 'devoted and faithful Muslim', who has fully accepted the Gospel message..with understanding of that message regarding Jesus Christ.....and he will proclaim without hesitation..."They told me Allah was the Almighty God...He isn't".
Yes, Salvation is open to Muslims...but you must be especially careful with terminology and understanding exactly what muslims mean, which is more times then not quite different then most assume when engaged about the things of the Christian God...the God of the Bible.
BTW...It's a long 'process' when working with Muslims....they will tell you that even after they might have accpeted Jesus Christ....as some have expressed...I said it but i still don't know what ti means. That's because in order to convert to Islam is simply a one liner sentence....so they think it's the same with Jesus.
Salvation is open to anyone who puts his/her trust in Jesus to deliver it. The only unforgivable sin is to never do that.
Just wanted to let you know that I had been responding to another post and believe the children of Abraham are children of faith of all nations, tongues, peoples, etc. Not just the Jews, because not all Jews are faithful. I don’t even want to think about the debate on Islam.
