14Heal me, Lord, and I will be healed;
Save me and I will be saved,
For You are my praise.
15Look, they keep saying to me,
“Where is the word of the Lord?
Let it come now!”
14Heal me, O LORD, and I shall be healed; save me, and I shall be saved: for thou art my praise.
15¶ Behold, they say unto me, Where is the word of the LORD? let it come now.
How does one know that they are a Christian? In this sermon on Jeremiah 17:14–15 titled “Healed From Sin,” Dr. Martyn Lloyd-Jones addresses the topic of assurance and provides tests of faith for believers to examine themselves. He elaborates that a Christian understands themselves to be not, primarily, a good person but instead a forgiven person. Moreover, the Christian knows that they do not merely do wrong things, but that the root of the issue is that they are diseased to the core and need more than moral reform in order to be free. In fact, what everyone needs is not behavioral change, but heart surgery. Additionally, they knows that they cannot do this surgery themselves; they need God to do the work in their heart. The Christian confesses that they are a sinner in need of a Savior. Therefore if one is a believer, then their only hope and boast are in God. The one who can fix the heart is the only one who is worthy of worship.
Dr. Martyn Lloyd-Jones
Dr. Martyn Lloyd-Jones (1899-1981) was a Welsh evangelical minister who preached and taught in the Reformed tradition. His principal ministry was at Westminster Chapel, in central London, from 1939-1968, where he delivered multi-year expositions on books of the bible such as Romans, Ephesians and the Gospel of John. In addition to the MLJ Trust’s collection of 1,600 of these sermons in audio format, most of these great sermon series are available in book form (including a 14 volume collection of the Romans sermons), as are other series such as "Spiritual Depression", "Studies in the Sermon on the Mount" and "Great Biblical Doctrines". He is considered by many evangelical leaders today to be an authority on biblical truth and the sufficiency of Scripture.
