Why didn't Israel go in and take the Promised Land at Kadesh Barnea?
Because they were steeped in unbelief, Israel did not go in and take the Promised Land at Kadesh Barnea. Although God told them He would drive out the Canaanites and said everything was ready—vineyards, fields, harvests waiting—they did not believe Him.
Les explains that Israel's failure at Kadesh Barnea was rooted in unbelief, not in any lack on God's part. God had told them He would drive the Canaanites out, and that everything was ready for them. They could go in and take the vineyards, fields, and harvests that were already waiting. The reason they did not go in was that they were steeped in unbelief. Les connects this same unbelief to Israel's later failure to recognize their Redeemer, King, and Messiah, even though the Old Testament prophecies should have made Him known.
