Not entirely, but that is part of it. "It is the Father's good pleasure to give you the Kingdom."
If you happen to receive material prosperity, then fine but do not aim solely for that. Besides, the Kingdom you refer to may not have anything to do with life in this present form.
Read a little further.
Luke 12:32 Fear not, little flock; for it is your Father's good pleasure to give you the kingdom.
33 Sell that ye have, and give alms; provide yourselves bags which wax not old, a treasure in the heavens that faileth not, where no thief approacheth, neither moth corrupteth.
34 For where your treasure is, there will your heart be also.
Do you know what Kingdom Jesus was referring to?
Jesus also said that His Kingdom is not of this world.
Read Hebrews 11:32ff and then come back and tell us how those heroes of the faith prospered materially.
Jesus also said "My kingdom is not of this world". If you miss that you totally misunderstand the gospel.
When the Lord told us to "seek first the kingdom of God and His righteousness" (Matt 6:33), that was in contradiction to seeking material gain. If we seek the kingdom, He promised that the basic things we need will be provided. If we seek material prosperity and forget the kingdom, we risk far more that loss of material benefit.
