Consider now, for the LORD has chosen you to build a house for the sanctuary; be strong, and do it. 1 Chron. 28:10
These are the words of David to His son to be strong and build the temple of the Lord as the Lord has chosen Him to.
God has chosen everyone for a unique purpose. He chose Noah to build an ark in order to create an escape from the coming wrath, Abram as the father of nations, Samuel as a prophet, Samson to defeat the Israelites in the promised land, David a shepherd boy as King of Israel, Paul to bring good news unto the gentiles and so on and so forth.
Similarly, He chose us for a purpose. Our ultimate goal must be to fulfill His purpose. May the Lord help us to accomplish what He has chosen us for. May He help us to be strong and do it.
