While there may be other, secondary reasons to obey God, that verse is specifically talking about rewards in heaven. If you don't believe that God will reward you in heaven, it is impossible to please God.

Hebrews 11:6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.

Matthew 7:19-21
Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal: but lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal: for where your treasure is, there will your heart be also.

The importance of heavenly rewards as a motivation for Christian living is a major theme of the New Testament. And it also debunks Catholicism and all forms of works salvationism. If a future sin could cost me all those heavenly rewards I had been storing up, the heavenly rewards would be just as fickle and the clothes on earth that get eaten by moths. And then I would have little motivation to serve God. So the whole system would fall apart.

Explain? The statement, "and it also debunks Catholicism and all forms of works Salvationism" Are you saying that a "sin" and depending upon the sin could cost your salvation - rewards?

1 John 5

16 If you see any brother or sister commit a sin that does not lead to death, you should pray and God will give them life. I refer to those whose sin does not lead to death. There is a sin that leads to death. I am not saying that you should pray about that. 17 All wrongdoing is sin, and there is sin that does not lead to death.

18 We know that anyone born of God does not continue to sin; the One who was born of God keeps them safe, and the evil one cannot harm them. 19 We know that we are children of God, and that the whole world is under the control of the evil one. 20 We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true by being in his Son Jesus Christ. He is the true God and eternal life.

And,

1 John 3

16 This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters. 17 If anyone has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in that person? 18 Dear children, let us not love with words or speech but with actions and in truth. 19 This is how we know that we belong to the truth and how we set our hearts at rest in his presence: 20 If our hearts condemn us, we know that God is greater than our hearts, and he knows everything. 21 Dear friends, if our hearts do not condemn us, we have confidence before God 22 and receive from him anything we ask, because we keep his commands and do what pleases him. 23 And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. 24 The one who keeps God’s commands lives in him, and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.

If I can help turn a person from the wrong to the right path – it would be a reward in itself. The reward is double fold because not only do I receive my own sins forgiven but also I helped turn someone’s life around – it is always a great opportunity to lead someone out of the darkness of life into the life of Christ - Light. Agreed? 2 Corinthians 4:6 ,For God, who said, "Let light shine out of darkness," made his light shine in our hearts to give us the light of the knowledge of God's glory displayed in the face of Christ.



19 My brothers and sisters, if one of you should wander from the truth and someone should bring that person back, 20 remember this: Whoever turns a sinner from the error of their way will save them from death and cover over a multitude of sins.
