In the Old Testament, we find that each prophet had a unique burden given to him by God – but all of them were concerned about the lack of holiness among God’s people.
The burden God lays on your heart is almost always an indication of the ministry He has planned for you. So, wait on the Lord to receive a burden from Him. If you serve the Lord without a burden, you will get bored with the Lord’s work after a while, and you are likely to end up seeking after money, man’s honour or earthly comfort. It is unfortunate that many who claim to be serving the Lord today have no God-given burden for their ministry.
