Strangers And Aliens (23c): Lions Are Real (1 Peter 5:6–11)

Occasionally, in Scripture, we are given glimpses of the spiritual realities behind the scenes, as it were. One thinks of the chariots of fire (2 Kings 6:15–17) that surrounded Elisha. They were present but unseen until Yahweh opened the servant’s eyes. In Zechariah 3:1–2 we are given a glimpse of a scene in which Satan is accusing Joshua the high priest. There is too that mysterious note in 2 Chronicles 21:1 in which Satan is said to have “stood up against Israel” (NASB95) and provoked David to perform a census in Israel. The spiritual realities and battles to which we are given an occasional glimpse burst, however, through the back curtain and on to center stage during the earthly ministry of our Savior Jesus. In the gospels we see Satan tempting Christ (e.g., Matt 4:1–11). He enters Judas (John 13:27) and demonic activity seems to increase dramatically during Jesus’s ministry (e.g., Matt 8:16; 8:29; 9:32; 12:22; 15:22; 17:18). Continue reading →
