Often, the call to service is not in the realm of your natural gifts. This means you must be available and looking for Him, rather than waiting to find your satisfaction in the things that are familiar to you.
Move ahead. Let nothing stop you. If He has called you, He will enable you.
In prayer, the focus must not be the knowing what lies ahead. You must be telling the Lord that you will follow Him one step at a time.
If you have served him for years, He will meet you in the freshness of His Life. If you have just met Him, He will meet you in the same way.
This is not about you. This is about Him.
