If Israel wanted to inherit the promises of God they had to be willing to believe that by stepping into the raging Jordan river during flood season God would stop the surging water so that they could cross safely over.
Those carrying the Ark were the chosen ones whose faith was put to the ultimate test as they would be the first ones to step into the flood. Let me say this, any who dare to take God at His Word will be tested as to what they truly believe! Faith does not ask “why?” or “how?” Faith steps forward by taking God at His Word! The people were told to consecrate themselves because of what they were about to experience! How many of us ever think about consecrating ourselves with the expectation of what we are about to experience in God’s presence! What matters is faith that believes God and trusts in His promises!
