It is no coincidence that Jesus’ temptation immediately follows his baptism. Many of God’s people have had similar experiences. Right after conversion or some other significant spiritual event, precisely when a certain level of victory or maturity seems to have been attained, temptations resume more strongly than ever (cf. Elijah in 1 Kgs 19:1–18 and Paul in Rom 7:14–25).
