His seal

2Ti 2:19  Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.

In a time of great confusion as to what it means to be a Christian, the seal, or stamp of God’s ownership remains the same.  First, God knows His own.  He is not confused or deceived by anyone.  Secondly, true children of God depart from iniquity.  True children of God live with a purpose to do right all the time, in every situation.
