Today, it is not unusual for believers to have unbelief. That’s right! It is possible to believe in God, Jesus, and the Holy Spirit and still have unbelief! Christians’ unbelief, however, has nothing to do with how much faith they have, for Christ says that they will be able to move mountains from one location to another, even if they only have faith (trust in God) that is the size of a mustard seed. What then is believers’ source of unbelief, if it isn’t their faith? On almost all of today’s spiritual matters that seem too farfetched to believe, especially as they compare with our rational, natural senses (seeing, hearing, smelling, touching, and tasting), we will display unbelief because we do not agree with God that we also have Christ’s supernatural power and authority.
This same unbelief in today’s Christians will make them as ineffective as Christ’s disciples once were. Even though Christ gave His 12 disciples His power and authority to handle ALL manner of sicknesses and diseases, and gave them the command to “…cast out devils…” (Matthew 10:1 and 8, KJV), they still couldn’t deal with the epileptic demon (that “him” the disciples refer to in the below Scriptures). They didn’t believe that the supernatural power and authority Christ had given them would cast out this kind of demon!
Thus, their unbelief, which was caused by their reliance on their natural senses, kept them from healing the boy. Likewise, when today’s Christians are confronted with unseen or unheard of before supernatural miracles, gifts, signs and wonders taking place, their first reaction is unbelief, even when they know that the WORD says believers can possess the power and authority of Christ to do great works—even greater works (a larger quantity of great works) than Christ did (cf. John 14:12). Christ, thus, confirms that fasting and praying are not for casting out demons; fasting and praying are the ways we cast out our unbelief about our supernatural abilities! AMEN.
“Then came the disciples to Jesus apart, and said, Why could not we cast him out? And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you. Howbeit this kind goeth out but by prayer and fasting” (Matthew 17:19-21, KJV).
