What does the Bible say about preparation for God's kingdom?

In Joshua 3, the preparation of the people of Israel to enter the promised land serves as a spiritual lesson for Christians. They were instructed to sanctify themselves, which highlights the importance of being set apart for God's purposes. This act of preparation is a crucial step before blessings can be received. The crossing of the Jordan River symbolizes a new beginning, illustrating that entering God’s kingdom requires spiritual readiness and obedience to His instructions, where we must look to Christ, our Ark, for guidance and salvation.
