A vessel of honour
If a man therefore purge himself from these, he shall be a vessel unto honor, sanctified, and fit for the master's use, and prepared unto every good work. (2 Tim 2: 21)
Within these words of Paul lies a secret. To be a usable vessel of God requires a pure heart. Those pure in heart will see God, they will also see Him at work through them. Are you prepared to be such a vessel? Then purify yourself before your God.
