God wants to give bless to believers - but for what reason? Psalm 84-86

You can't help but read these three Psalms and see the truth that God wants to and does bless His children. In 84:11 we see that God holds no good thing from those who walk uprightly. The writer goes on to say, "... how blessed is the man who trusts in You (God)!" But, for what reason does God bless us? In 86:17 we see the writer asking God for a "sign for good, that those who hate me may see it and be ashamed ...". God does want to bless us but His blessing is not simply for our comfort (although He certainly longs for that for us). God wants to bless us so that we can show Him off to others. He doesn't simply bless us with benefits and possessions so that we can boast to others regarding what we have obtained. God is pouring out His favor on us so that we can brag about Him. He simply wants us to obey so that we can be in a place He can bless us. God wants us to be trophies of His mercy and grace. Let's not rejoice that we HAVE possessions. Let's rejoice out load that we have possessions and blessing because HE looked on us with His favor.
