Dee, Jesus didn't come to save us from Islam, but from sin. Rome had conquered the world with pagan idolatry and syncretism, and yet He left Rome alone and conquered the real threat - sin and death. While He did that He also taught us to love our enemies and to bless those who persecute you. Not long after He ascended, maybe less than 40 years by some accounts, Rome fell ... from the inside.
I'm not called to warn the world against the evils of Islam, but rather the evil of sin in our own hearts. The lust of the eyes, flesh and pride of life. And to call sinners to repentance in faith in Christ alone, and to walk in the light.
Islam is an empty hollow religion full of hate and violence, like all religions, like even Christianity can be ... bur faith is different than religion, and I am called as a pastor/teacher to build up the people of faith.
Islam is not the threat, sin is. Islam is a tool of Satan to keep men lost, to take glory away from God and to fill the Christian church with hate and fear so that we do not fulfill the great commission. After years of bearing the sword for my country, in Muslim lands, learning the language, culture, religion of the enemy, I went to live there with my family for years as missionaries. God is building His church of followers of Christ in the middle of the axis of terror; I've discipled pastors, worshipped with small groups. God is raising them up to shine His light from the inside out, and like Rome they will collapse from the inside out.
