Let me present a brief summary of these conditions as taught by the Bible and repeated through the centuries by the holiest, sweetest saints the world has ever known:
First, we must forsake our sins. The belief that a holy God cannot be known by men of confirmed evil lives is not new to the Christian religion. The Hebrew book, The Wisdom of Solomon, which antedates Christianity by many years, has the following passage: "Love righteousness, ye that be judges of the earth: think of the Lord with a good heart, and in simplicity of heart seek him. For he will be found of them that tempt him not; and showeth himself unto such as do not distrust him. For froward thoughts separate from God: and his power, when it is tried, reproveth the unwise. For unto a malicious soul wisdom shall not enter; nor dwell in the body that is subject to sin. For the holy spirit of discipline will flee deceit, and remove from thoughts that are without understanding, and will not abide when unrighteousness cometh in." This same thought is found in various sayings throughout the inspired Scriptures, the best known probably being the words of Christ, "Blessed are the pure in heart: for they shall see God."
Second, there must be an utter committal of the whole life to Christ in faith. This is what it means to "believe in Christ." It involves a volitional and emotional attachment to Him accompanied by a firm purpose to obey Him in all things. This requires that we keep His commandments, carry our cross, and love God and our fellow men.
