What Admonish Means
  Parents are taught to rear their children in the nurture and admonition of the Lord (Ephesians 6:4). Paul said the things written aforetime were written for our learning and admonition (Romans 15:4; First Corinthians 10:11). Romans 15:4, "And I myself also am persuaded of you, my brethren, that ye also are full of goodness, filled with all knowledge, able to admonish one another." We admonish each other in psalms, hymns and spiritual songs (Colossians 3:16). So go many passages of Scripture.

  To admonish means to instruct, counsel, warn, reprove, rebuke, teach, advise, bring to mind what we may already know but that which needs to be ever brought before us. This is a task that is a privilege and opportunity that will be ours as long as we live as Christians in this life. By this effort we can render service to God and others. Let us not neglect it.
