God-given vision is a mental picture painted by the Lord to clarify the truth for man to understand. By the vision given to Peter, the barrier that hindered the preaching of the gospel to the Gentile world was broken. Vision gives boldness, drives away doubts and strengthens your belief. Much success was achieved by the early Church in its evangelistic outreach through visions. By vision, Ananias was emboldened to minister to Saul of Tarsus.
It is wonderful to know God's word but we are only blessed when we practice the Word. The knowledge of the truth alone will not make us free, but the doing of the truth. You are deceiving your own self when you do nothing with the knowledge of God's word, that you have. Faith comes by hearing, and hearing by the word of God - Romans 10:17. But faith without works is dead. The Lord Jesus has commanded us to learn of Him by following His examples to do as He has done.
Because of the sin of Adam, every man is born into the world with inherited sin, apart from Jesus - the seed of the woman. And no one can cleanse himself from sin or help another man. Only Jesus can transform a sinner into a saint by cleansing them with His precious blood which was shed for many for the remission of sins. Jesus stands at the door of your heart, knocking, that you may let Him in.
Idle words are useless and they are very destructive. Lying, jesting, swearing, cursing, gossiping and all evil speaking should be avoided. They come from the unbridled tongue of the unregenerate soul. Endeavour to hide the word of God in your heart; it will cleanse and keep your tongue from uttering corrupt communication. If you keep God's word within you; they shall withal be fitted in your lips - Proverbs 22:18.
The works of the flesh will manifest wherever the flesh is in control. As long as you live in this body of clay, your members (eyes, ears, hands, feet, tongue, etc) will be tempted to lead you into sin. Even Jesus was tempted while in the flesh but glory be to God; He overcame. To overcome like Jesus, you must yield your body to Him with the strong determination to always obey God rather than men.
