John 14:27 Peace I leave with you, my peace I give unto you: not as the world give, give I unto you. Let not your heart be troubled, neither let it be afraid.
As the Prince of Peace (Isa. 9:6), Jesus leaves us with His peace that passes all understanding. We must permit this peace to garrison or keep our hearts and minds through Jesus Christ (Php. 4:7). Start with renouncing all worry and then by prayer, supplication, and thanksgiving, make all your requests known to God (Php. 4:6; Jas. 4:7). We must always think on the right things (Php. 4:8) and keep our minds stayed on God (Isa. 26:3). Use the weapons of spiritual warfare (2Cor. 10:4-6) when the enemy attacks your mind and put on the whole armour of God so that you are able to stand against the wiles of the devil (Eph. 6:10-18). Have faith in God (Matt. 6:25-34; 7:7-11; 17:20; 21:22; Mark 11:22-24) and live and walk in the Spirit (Gal. 5:16-26; Rom. 6:14-23; 8:1-13). Do not cast away your confidence in Him (Heb. 3:6, 12-14; 6:11-12; 10:19-23, 35-39) but cast all your cares upon God (1Pet. 5:7).
According to 2 Timothy 1:7 God has not given us the spirit of fear; but of power, love, and of a sound mind. He gave us a Spirit of boldness (Rom. 8:15); a Spirit of power (Luke 24:49; Acts 1:8; 1Cor. 16:10; 1Tim. 4:14); a Spirit of love (1Cor. 13:4); and a Spirit of a sound mind, understanding, and judgment (Gal. 5:22-23). The spirit of fear mentioned here is the Greek word deilia meaning cowardice. When we do fear we lose our power, love and sound mind. That’s why your mind becomes frenzied in fear or with worries. This is one of the first stages of backsliding. What you fear will come over you. You give permission to fear to manifest it in the physical reality. That is the enemy’s greatest power against all men. He brings the thought, we think upon it and make it ours and it will come to pass (Job 3:25).
‘Power’ the Greek word dunamis means a power to reproduce itself, implying the need for constant activity and use for continued reproduction. From this word, we get our English dynamo and dynamics – the branch of mechanics dealing with the principles of motion or active operation. Just as a dynamo needs to be in motion to produce power, so one needs to stir up into flame the gift of God in his life (2Tim. 1:7; 1Tim. 4:14).
