Scripture : '... he gave them power and authority over all the devils, and to cure diseases' Luke 9:1
When God calls somebody for His purpose He equips him by giving him authority and power to heal the people, to cast out demons, to cure diseases and soothe the pain. In order to fight against the wiles of the devil, which moves in every direction to bring chaos in the lives of the people, God gives His children authority in His name to bind the forces of evil and darkness and set the people free. When Jesus Christ, the Son of God, during His ministry of three and half years on this earth, trained His disciples and sent them pair by pair, He gave them power and authority over all demons and to cure diseases. He sent them to preach the Kingdom of God and heal the sick.
The LORD began to use the disciples and they reported to the LORD the works of God which was done through them. Similarly in these last days while the devil is like a roaring lion and like a snake trying to devour God's children, the LORD has given you authority and power to tread on serpents and scorpions and over all the power of the enemy. Nothing shall by any means hurt you. The LORD also warned them not to rejoice when the spirits are driven away. He asked them to give glory to God for the LORD was using them.
For God to use you, you should surrender your life totally to God and be forgiven of your sins and dedicate yourself to lead a holy life. Then the burden for God's Kingdom in you will make you find grace in His sight. Submit yourself today to be used by God for His purpose.
Prayer : LORD, thank Thee for giving me the authority. Amen.
