The context of this is a promise from God to the Jewish exiles in Babylon. 70 years are going to pass before deliverance. Thus, this text does not fit well with the health, wealth, and prosperity idea that God at any moment is going to give all your hopes and dreams, which is often how it is used. Most of the generation who received this promise would never see its fulfillment.
The thing is, God’s priority is not our plans, His priority is His own plan. And His plan was to deliver Israel, but not for 70 years, and so most would be dead before it would occur. In a sense, that’s disappointing news. If you think God is a vending machine to fulfill your dreams, think again. He is Lord, and His ultimate plan for His people is to make them more like Christ, and often that’s through a life of hardship and suffering.
So using this text is fine, as long as we submit to the fact that what God has decided is best for us, might include suffering rather than temporal prosperity.
