Jesus commanded believers to focus on spiritual realities and to set their hearts on heaven, not earth. If you really do this, you will surely be willing to invest all your time and energy in all that heaven has to offer instead or seeking earthly riches.
“Do not store up for yourselves treasures on earth, where moths and vermin destroy, and where thieves break in and steal. But store up yourselves treasures in heaven, where moths and vermin do not destroy, and where thieves do not break in and steal. For where your treasure is, there your heart will be also.” Matthew 6:19-21
Yes, you still should set money aside for retirement. Surely don’t give all your life savings away to missions and have nothing left to sustain you in your old age. The key is, you should still invest heavily in spiritual things.
I’m seeing so many people who are giving everything they have to the Mega Churches and are preaching a false doctrine. People end up giving away life savings to the already rich so called pastors and end up having nothing left to live on. Others tend to spend so much money on materialistic items that has no value in heaven. Most of us are caught up on living a lavish life and don’t realize that you can’t take the things of this world to heaven with you. Stay focused on storing up your treasures in heaven instead of this earth!
