Obedience is better than sacrifice.
When a believer does what the Word of God calls him to do, the glory of God will manifest.
This is a great promise from the Lord of Glory to His called out ones.
If you are called to preach, preach. If you are called to teach, teach. If you are called to serve, serve. If you are called to give, give. The glory of the Lord will be seen upon and by you and those you minister to.
