To reach any goal in life requires consistency and work. God has different work for different people, some are sent to do some things, others are sent to work in other areas. The Bible teaches us different ways to work in the Kingdom of God.
God calls to work with HimHaggai 2:4 
"Yet now be strong, Zerubbabel; says the Lord; and be strong, Joshua, son of Jehozadak, the high priest; and be strong, all you people of the land; says the Lord, and work; for I am with you, says the Lord of Hosts." To work for Jesus requires sacrifice, and the Bible encourages us to keep going forward.
God calls for immediate workMatthew 21:28 
"But what do you think? A man had two sons, and He came to his first and said, Son, go work today in my vineyard." Sometimes, the tasks that we have to do require time, but sometimes we need to do it right now. These are the words in this verse.
