“And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him.” (Heb. 11:6 ESV) 

According to the above passage, there are two things that make up the kind of faith that pleases God: 1) believing that He exists, and 2) believing that He rewards those who seek Him. Most people typically find it easy to believe in the existence of a God, but many struggle with the second belief—that He rewards those who seek Him. But when you think about it, it shouldn’t be a stretch; just as parents love to give gifts to their children, God does, too. 

“If you then, who are evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask him!” (Matt. 7:11)

“Every good gift and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or shadow due to change.” (James 1:17 ESV)

Therefore

“Henceforth there is laid up for me the crown of righteousness, which the Lord, the righteous judge, will award to me on that day, and not only to me but also to all who have loved his appearing.” (2 Tim. 4:8 ESV)

“Whatever you do, work heartily, as for the Lord and not for men, knowing that from the Lord you will receive the inheritance as your reward. You are serving the Lord Christ.” (Col. 3:23-24 ESV)
