I recall the words of the Apostle Paul, how in confidence he declared that the Lord would rescue him from every evil attack and bring him safely into his heavenly kingdom.
I think it's true that when God is present and doing a work, that the enemy the devil is sure to attack at some point. Charles Spurgeon once said that the greatest sign of the Lord's presence is the devil's roar (like a lion). Some truth in that. At least we can expect evil attacks in this life, and we must be ready for them.
Jesus himself experienced this when challenged by Peter not to take the way of the cross. Peter was at that moment an opposer, but it's likely the opposer himself, Satan, was in Peter's words. So we have to be ready for attacks both from within- ourselves, and from without- others. Many subtle and others not so subtle.
I've experienced a few of these lately, and hopefully I'll benefit from them. God is at work to use those very attacks for my good and growth in his grace, and of course, for his glory. This is not to say that our lives consist of being attacked, but simply that we must be ready when it does happen.
What might you like to add to this?
