Mark 6:13 They drove out many demons and anointed with oil many people who were ill and healed them.
How could the disciples go out and heal the ill and drive out demons from people?
They listened to Christ and obeyed Him. When God asks us to step forward and do things, things which we may doubt or be afraid of, we can be sure it is the right thing to do!
God wants us to succeed in working with Him. He wants us to have an abundant life. He has a plan. We just need to follow that plan!
