The reality is, regardless how long someone is saved, there are some aspects of Christ a person will never learn if he is not taught and does not study. Some aspects will not be learned if a person does not serve. Some aspects will not be learned if a person does not witness. Some aspects will not be learned if a person does not learn to wait on the Father, trust Christ with no obvious evidence beyond the Scripture, have enemies to pray for, stand alone and speak the truth in love, walk humbly, experience the blessing of the Mount of Transfiguration as well as the loneliness of Gethsemane, and live thankfully for all things in all times.
“But speaking the truth in love, we are to grow up in all aspects into Him who is the head, even Christ” Ephesians 4:15.
