What does the Bible say about spiritual preparation?

Spiritual preparation is vital for engaging with God's plans. In Joshua 3:5, the Israelites are instructed to sanctify themselves in anticipation of the wonders God would perform. This sanctification signifies separating oneself from worldly influences and focusing on God's holiness. Similarly, Amos 4:12 highlights the necessity of preparation to meet God, urging people to be spiritually ready. It reflects a principle that transcends time: God's people should always be in a state of readiness, recognizing His impending actions.
