You can do it
One day, God ministered to me from His word in matt. 14:28 (And Peter answered him and said, Lord, if it be thou, bid me come unto thee on the water). He said “ when I tell you to do anything, I won’t be at the other end watching to see if you will do it right or wrong (trial and error) No!, I tell you to do a thing because the ability to do such is inherent in you(had been created at the instance God spoke it) God will not say to you to do a thing that you can not do. Whatever God says to you to do, no matter how big or how ambiguous it is, you can do it. Prior to that particular moment, peter might not have known that he could walk on water, maybe the other disciples in the boat would have thought that peter was being foolish to step out and walk upon the water to Jesus until they saw he could do it. Trust God’s leadings always, he always knows better. You can do what ever He tells you to.
