I agree!
I always look forward to trying to change the heart of muslims, it stresses me most of the times mostly because of lack of knowledge of the Word of God, but I will always give it my best shot. And just to see one muslim convert to a child of God will bring me great joy and to me that is an incentive. I usually quote scriptures because to me they are powerful against the enemy such as: Hebrews 4:12 - For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
I try to remain calm because it gets rough around here sometimes, so I concentrate on this scripture.
And the servant of the Lord must not strive; but be gentle unto all men, apt to teach, patient, In meekness instructing those that oppose themselves; if God peradventure will give them repentance to the acknowledging of the truth; And that they may recover themselves out of the snare of the devil, who are taken captive by him at his will. 2 Timothy 2:24-26
