In their way up to the top, the candle asked the man, "Where are we going?"
"We're going to the top of this lighthouse and give signals to the big ships on the ocean," the man answered.
"What? How could it be possible for me with my small light to give signals to those big ships?"
"They will never be able to see my light", replied the candle weakly.
"That's your part. If your light is small, let it be. All you have to do is keep burning and leave the rest to me", said the man.
A little later, they arrived at the top of the lighthouse where there was a big lamp with a loop behind it. Then the man lit the lamp with the light of the candle and instantly, the place shone so brightly that the ships on the ocean could see its light.
With our being and our limitations, we're hardly able to do any meaningful things. Yet, one thing you should bear in mind is that your life is like a small candle in God's powerful hand. All your abilities and expertise will remain as a small light if you don't put your life in God's hand. On the contrary, even if your light is so small or dim, if you entrust all your life to God, he is able to make your small light into a big one that brings blessings to many people.
Even it wasn't impossible for Joshua, who was Moses' servant, to feel slightly fear when God ordered him to lead the Israelis invading the Canaan. God comforted and strengthened Joshua that He would never leave him. God even promised him victory over victory. All God asked from him was, "Be strong and very courageous. Be careful to obey all the law my servant Moses gave you; do not turn from it to the right or to the left, that you may be successful wherever you go." (Joshua 1:7)
Do not look at your inability, limitations, and weaknesses. God entrust you with something, whether it is a work or a ministry. Have faith that you are in His mighty hand that He will use you according to His will. When we put all our trust in Him, we will see how He uses our lives, including our limitations, to be blessings to others.
