Is it Okay to Want Rewards

Are Christians wrong for wanting rewards in heaven? Should a believer in Jesus have guilt for serving God with the hope of receiving God's recognition, not in payment for sin but for serving as a believer in Jesus? Does the Bible mention rewards? Does God speak to this innate desire we have to be rewarded? Matthew 6:19–21: “Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal, [20] but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. [21] For where your treasure is, there your heart will be also. (ESV) To be good stewards, we must have some guiding principles for managing all that the Lord God has given to each of us. Many have taught that Grace Giving is the New Testament concept for giving to the Lord. I am not arguing with that, but for centuries, the church has taught that tithing is the first step of Grace Giving, which is a good thing. It was the first method used by God to teach His people stewardship. It was the first method God used to finance His Kingdom work among men. It was and is the elemental principle of giving. If the principle of tithing is not settled in your heart and life, you will never move beyond it. Talk of Grace Giving can fill the airwaves, but unless God’s people solidify their belief in tithing, they will never move beyond its essential concepts.
