And Joshua said to the people, “Sanctify yourselves, for tomorrow the LORD will do wonders among you.” (Joshua 3:5)
As the people of God were getting ready to enter their promised land, God told them to sanctify themselves because God was going to do wonders among them the next day. Notice this was something they had to do rather than something God would do for them.
Do you want to see God do wonders among you? Then sanctify yourself! Sometimes we have to walk in a deeper level of consecration to God in order to experience God at a deeper level.
“Therefore, having these promises, beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.” (2Cor. 7:1)
