"O LORD, by your hand save me from such men, from men of this world whose reward is in this life" (Ps 17:14).
There are two types of people in the world. There are those whose activities are designed to generate a reward in this lifetime. And there are those who live to generate a reward when they meet our Lord in Heaven.
Not every Christian models the latter. How does one judge whether they are living for the future reward versus the earthly reward? There are several key indicators.
Future reward people tend to be givers. They make their time and resources available to be channeled for Kingdom purposes. They realize their sowing will ultimately be rewarded at the Judgment Seat of Christ where what they have done on earth will be judged and rewarded by God (2 Corinthians 5:10).
Future reward people live a life based upon obedience-based decisions. They don't make decisions based on their perceived outcome. They realize a decision based on obedience alone may not result in an immediate outcome. Jesus was obedient to the cross, but the immediate outcome was His own death on the cross.
Future reward situations show up in daily life in a number of ways. Perhaps a person has wronged you and God calls you to forgive and even bless that person without expectation of their response. Perhaps God calls you to sow money into a ministry or another person's life without expectation of return from them. Perhaps you are called to serve another person without expectation of any earthly reward. The situations we might encounter are unlimited.
Are you living a life based on a future reward, or short term reward? Today, evaluate how you make decisions and how you allocate resources. This will reveal whether you are a future reward Christian.

Serenity Prayer 

God grant me the serenity
to accept the things I cannot change;
courage to change the things I can;
and wisdom to know the difference.

Living one day at a time;
enjoying one moment at a time;
accepting hardships as the pathway to peace;
taking, as He did, this sinful world
as it is, not as I would have it;
trusting that He will make all things right
if I surrender to His Will;
that I may be reasonably happy in this life
and supremely happy with Him
forever in the next.
Amen.
