Here's a tension worth sitting with: Scripture tells us "Jesus Christ is the same yesterday and today and forever" (Hebrews 13:8), and that "I, the Lord, do not change" (Malachi 3:6). And yet Scripture also tells us the covenant itself changed. "The days are coming," declares the Lord, "when I will make a new covenant" (Jeremiah 31:31), and God promises to give His people "a new heart" and to put His Spirit "within you" (Ezekiel 36:26, 27).

Imagine the scene: a loud, sudden wind fills a room in Jerusalem during one of the busiest festival weeks of the year. Tongues of fire appear over the heads of a group of believers. They begin speaking in languages they've never learned, clearly and intelligibly. A crowd gathers from every direction, confused and amazed, murmuring theories about what's happening and whether these people have simply had too much wine. In the middle of the chaos, one fisherman-turned-apostle stands up and says, "Let me explain this to you and listen carefully to what I say" (Acts 2:14).

Uma das mudanças mais notáveis na história do povo de Deus é como o Espírito Santo redefine nossa abordagem à pureza, à santidade e ao ministério. Sob a antiga aliança, o foco era a proteção - manter o que era sagrado separado do que era impuro. As regras e os rituais eram projetados para proteger contra a contaminação, criando limites que mantinham a santidade contida.

O homem levantou a cabeça e olhou diretamente para mim: "Nunca oraram por mim com tanta gentileza e bondade - e eu recebi muitas orações por meus problemas ao longo dos anos!"
