Psalm 50

In verses 14 & 15 the psalmist lists three things that are acceptable sacrifices. 1-giving thanks to God. When we do this we lower ourselves in our own eyes while elevating God. 2-give as we have promised. The vow under the Law is just as true today. When we make a promise to God we display our faith most clearly when we deliver on our promise. 3-call on God when we face difficulties. To live depending on God to provide is one of the greatest acts of worship.
