And the Lord said to Satan, “From where do you come?” So Satan answered the Lord and said, “From going to and fro on the earth, and from walking back and forth on it.” – Job 1:7
What is Satan doing everyday? “…going to and fro on the earth, …walking back and forth on it.”
He is seeking whom he may devour, walking about like a roaring lion – this is what the Apostle Peter tells us in 1 Pet 5:8. He is really busy doing this everyday.
If Satan is busy doing this everyday, we need to be busy on our guard. We need to take offensive measures against him as our best defense strategy. What should such offensive measures include? Obviously – the means of grace bestowed by God. How important it is that we should use these means for our own good and not take the threat of Satan lightly. Hence, don’t neglect the means of grace – the word, prayer, Christian fellowship, worship, breaking of bread, etc.
