1 Chronicles is written as the Israelites return to Jerusalem after spending nearly 70 years in exile in Babylon. They were struggling to put their lives back together, from reestablishing the city to rebuilding the temple to renewing their relationship with God. In chapter 16, they brought the Ark of the Covenant back to its rightful place in Jerusalem after having been captured by the Philistines. In thanks to God, David ordered that sacrifices be offered to God, and they sang this song of praise for God's faithfulness. His unfailing mercy was the Israelites’ assurance that they could always depend on Him to save them. Salvation is not just for the ancient Jewish people or any other elite or special group but for "all the earth."
Not only should we share God's marvelous works among one another as believers, but also with the lost. The Lord's salvation is a free gift to everyone who comes to believe. It is now every believer’s responsibility and privilege to take His Good News to every corner of the earth so more and more people can enjoy the freedom of salvation.
The God who saved the Israelites is the same God we have today. No matter how hopeless our situation appears, we can trust Him to restore and renew us. Let us sing to the Lord for His faithfulness and mercy! He is the God who saves.

Dear Heavenly Father, I sing praise to You for all You have done for me. You created this beautiful world and filled it with miracles. Unfortunately, many of us have taken them for granted. I pray that more and more people will see Your goodness and realize that You are the Creator, Protector, and Sovereign God. May everything I say and do give You honor and glory. Let Your presence encourage and comfort me as I face the challenges in my life. Thank You for Your forgiveness, mercy, and unconditional love for all of us. 
In Jesus's name I pray. Amen.
