What you are equating a lion with? Man, Satan or God? If satan, then know this, satan may be able to attack or even kill someone, but he has no right to the spirit of a true christian that is bought by His blood. So don't be fooled into believing that just because a person is a christian that they can not be harassed and attacked. There could be all sorts of reasons for them to do so, but we need to recognize what is happening and ask God for strength to endure. Christians can not use the devil as the reason they fall. He instigates, whispers in our ears, and tempts us...but that is when we pray and pull our scriptures and tell him No. This is what the Lord God says and read that scripture and believe it to make satan flee. We are held accountable before a just God. Satan will have his day as well. There is no fear of hell for those that know God.
