Ananias was sent to Saul that he might be filled with the Holy Spirit. Paul was definitely and consciously filled to visit judgment upon Elymas. These are not my figures, but God's. Sin today is lightly regarded by a heedless, godless world, and too often also by professing Christians. We need a new realization of sin as awful and abhorrent, as cursing and damning.
Sin is sin.
If ever we are to be filled with the Holy Spirit, we must reckon frankly and fully with our sins. There must also be a simple reliance upon God's word of promise. We must trust Him to lead us into the realization of life. The filling of the Spirit brings manifold results. We shall, for instance, be at rest.
