Sometimes you may feel small. These are lies from Satan. We were all created and destined for purpose.
When God told Deborah to tell Barak to go and fight against the enemy, he was afraid and asked Deborah to go with him. She boldly went with him. But the victory went to Deborah. God used a woman to win the battle, this was an uncommon victory but God trusted her greatly.
You’re not insignificant or so small that God cannot use you. No matter how unimportant you may feel, God can and will trust you with big things. Have faith!
