When speaking to people about our faith and seeking to make them think about their situation before God, what are we to say? There is always the danger, when interacting with religious people, of getting involved in a religious melee as we wrestle about ideas and experiences.
One thing I often tend to do particularly, when speaking to a Muslim for the first time, is to focus on the issue of assurance. I ask them about on what basis they hope to get to heaven. Pretty much always they will say that it has to do with their works. I then tell them of the contrast with the true message of sins forgiven in Jesus Christ. The message of the Muslim, as with all other religions, is a miserable message which has no assurance of eternal blessing. It is essentially a message about doing your best and see if your good works outweigh your bad works on the day of judgement. The message of full and free forgiveness in Christ is so different.
One of the impacts of this is that I am refreshed in knowing how wonderful the Gospel is. I am always left wondering why someone would choose the pitiful gunge of false religion which always depends on our efforts. How can anyone prefer that to the wonderful news of a full and free salvation in and through Jesus Christ our Lord?!
