It's Independence Day week in America. As we ask God to continue to bless America, we should remember two things: 1) Let's give thanks for the fact that He already has blessed us abundantly, and 2) Let's remember the reason He blesses a nation, as His word tells it in Psalm 67 quoted above-- God's blessing on a nation is so that He will be known in all the earth, through His people's witness, and so His great salvation will be experienced by all peoples.
We know it is a time of economic downturn; however, even now Americans are the most financially blessed people on the earth, and much more so than other lands. We also know that our country has seen a spiritual and moral decline in our generation; however, even now we are among the most blessed nations on earth, with religious freedom, a strong evangelical church, and unlimited availability of the word of God and the proclamation of it in our land. Much has been given to us already, and much is required of us. Most of the world does not have either the financial blessing or the spiritual blessings we take for granted. God didn't bless America because He liked us better than everyone else. He blessed us because He wanted us to be a blessing to other nations, and to proclaim His glory around the world.
So even if times are tough, I encourage you to be involved in Great Commission works around the world, so that God has a reason to continue showering our land with His favor.
