"Ye have said, It is vain to serve God: and what profit is it that we have kept his ordinance, and that we have walked mournfully before the LORD of hosts?
And now we call the proud happy; yea, they that work wickedness are set up; yea, they that tempt God are even delivered."-Malachi 3:14-15
In this passage of Scripture, the Lord rebuked His people for their distorted outlook on the benefits of righteous living versus the benefits of wicked living. We see that they have a problem right away when they say, "...what profit is it that we have...walked mournfully before the LORD of hosts?" (V. 14) The problem here is that, instead of being filled with the joy of the Lord, they focused on the sorrows they had faced along the way. Instead of remembering the countless miracles the Lord had worked in their midst, as well as the multitudes of victories He had given them over their enemies, they concentrated on the sorrows and heartaches they had experienced - all the while failing to remember the pain and suffering they had endured before they knew God.
Not only did they believe that serving God was futile; they also considered the wicked to be better off than they were. They didn't realize that they wages of sin is death (Romans 6:23). They believed sinful living brought happiness as well as deliverance (V. 15), thus leading them away from the Lord.
I once heard a minister say that, given enough time and opportunities, our feet will eventually catch up with our heart. If our heart desires the things of the world, then it won't be long before we start pursuing the things of the world.
We've got to place our heart in God's hands; that way, following it will always lead us back to the cross!
"...for the LORD your God proveth you, to know whether ye love the LORD your God with all your heart and with all your soul."-Deuteronomy 13:3
