J. C. Ryle (May 1816 – June 1900), wrote the following:
There is a faith which is vain and useless, as well as a faith which justifies and saves. How shall a man know whether he has true saving faith? The thing may be found out! The Ethiopian may be known by the color of his skin; and the leopard may be known by his spots. True faith may always be known by certain marks. These marks are laid down unmistakably in Scripture. Reader, let me endeavor to set these marks plainly before you. Look at them carefully—and test your own soul by what I am going to say.
He who truly believes in Christ—has a NEW HEART. It is written, “If any man is in Christ, he is a new creature—old things are passed away; behold, all things have become new.” (2 Cor. 5:17.) A believer has no longer the same nature with which he was born. He is changed, renewed, and transformed after the image of his Lord and Savior. He who minds first, the things of the flesh—has no saving faith. True faith, and spiritual regeneration, are inseparable companions. An unconverted person—is not a genuine believer!
He who truly believes in Christ—is a HOLY person in heart and life. It is written that God “purifies the heart by faith,” and that Christians are “sanctified by faith.” “Whoever has this hope in him, purifies himself.” (Acts 15:9; 26:18; 1 John 3:3.). A believer loves what God loves—and hates what God hates. His heart’s desire is to walk in the way of God’s commandments, and to abstain from all manner of evil. His wish is to follow after the things which are just, and pure, and honest, and lovely—and to cleanse himself from all filthiness of flesh and spirit. He falls far short of his aim, in many things. He finds his daily life, a constant fight with indwelling corruption. But he fights on—and resolutely refuses to serve sin. Where there is no holiness, we may be sure there is no saving faith! An unholy man is not a genuine believer!
He who truly believes in Christ—overcomes the WORLD. It is written, that “whoever is born of God, overcomes the world—and this is the victory which overcomes the world—even our faith” (1 John 5:4). A true believer is not ruled by the world’s standard of right or wrong, of truth or error. He is independent of the world’s opinion. He cares little for the world’s praise. He is not moved by the world’s censure. He does not seek for the world’s pleasures. He is not ambitious of the world’s rewards. He looks at things unseen—he sees an invisible Savior, a coming judgment, and a crown of glory which never fades away. The sight of these objects, makes him think comparatively little of this present world. Where the world reigns in the heart—there is no genuine faith. A man who is habitually conformed to the world—is not a genuine believer!

Many people in today’s world seem to think they can be a true believer in Jesus Christ, and yet not obey His commandments or follow His teachings and example. If we TRULY have faith in God – it WILL impact and change our lives! That doesn’t mean that it will be an instant change of course, just like many things in life, some people take longer to learn than others, and some people are SO eager to truly KNOW God that they willingly pay whatever the cost to know Him and seek Him and become like Him, while others sit on the sidelines for years contemplating whether the “cost” is worth it.
Jesus Himself answered that question, “Come to me, all who labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn from me, for I am gentle and lowly in heart, and you will find rest for your souls. For my yoke is easy, and my burden is light.” (Matthew 11:28-30)
