There was a time when Jesus and his disciples were on a boat. As Jesus slept, a storm approached and as it grew stronger causing water to enter the boat, the men feared for their lives. They woke Jesus up asking that He save them because their lives were surely in danger. When Jesus woke up He asked why the men were so afraid and said "O you of little faith"; then Jesus stood up, rebuked the storm and then, the storm was gone, The guys were in awe and were like, "who can this be that even the winds and the sea obey Him?" (Matthew 8:23-26)
There was another time when the disciples were out on the boat. Jesus was not with them at that time, but eventually, they saw Jesus walking on the water toward them. They freaked a bit and thought maybe it was a ghost, but Jesus spoke out to let them know that it was indeed Him. Peter called out to Jesus and asked to prove that it was indeed him and told Jesus to command that Peter too walked on the water. So Jesus did, and Peter walked on water; until a wave came and became afraid and started to sink. Jesus pulled him up to safety and once again said "O you of little faith, why did you doubt?"
(Matthew 14:25-31)
Doubt and Fear have been the enemy of God and His children from the very beginning as read in Genesis regarding the fall of man, Adam & Eve disobeying God. They are strong adversaries and more often then not, doubt and fear find a way into our hearts causing us to miss out on the blessings God has for us and miss out on being witness, through personal experience, to the power and never broken promises of God. Doubt says miracles don't happen anymore. Fear says I'm not good enough and will never be good enough for God to bless me. Let me tell you something about doubt and fear; they are the spawn of lies which smoothly slithers out of the mouth of God's enemy. There is a weapon that is available to all of us that can and will defeat the lies of doubt and fear; and that weapon is faith. It's not just any faith, but the faith of a child.
A child's faith is unwavering, it's raw; a child has perfectly blind faith. When the disciples asked Jesus who was the greatest in the kingdom of heaven, Jesus pointed out a child and said "unless you are converted and become as little children, you will by no means enter the kingdom of heaven. Therefore, who ever humbles himself as this little child is the greatest in the kingdom of heaven..." (Matthew 18:1-4). Obviously a grown adult cannot magically transform into a child. However, as adults we need to be as humble as a child, unconditionally loving like a child, fully trusting like a child and as faithful as a child to God. That means believing in and having faith in God; as a child would. Where is your faith; where on the line of adulthood does your ability to be like a child lay?
