Joshua told the people, “Sanctify yourselves, for tomorrow the LORD will do amazing things among you.” Joshua 3:5
I think it’s really important to try to get rid of things that make us sin. Integrity is necessary to really show people Jesus through us, and if we ‘sanctify’ or ‘consecrate’ ourselves, we set ourselves apart ready for God to use for his glory. Of course, God uses sinners all the time because we are all sinners. But I think we should pray that God would reveal to us our sins so that we can become closer to him.
