“The Mighty One, God the Lord, speaks and summons the earth from the rising of the sun to its setting.” – Psalm 50:1
This is the first of a dozen psalms in the original Hebrew text to be attributed to Asaph. Here in the first verse of this psalm Yahweh is given three lofty and frequently used OT titles. This majestic reference to God resembles that found throughout the Mosaic texts. The entire earth is summoned forward by the great judge to receive its verdict. These three magnificent titles, used back to back, call forward an unequaled level of greatness and adoration.
Effortlessly our Father calls before himself every inch of the earth, from the past, present, and future. Every nation is subject to his rule and judgment. There is no excuse or reprieve for the ignorant or obstinate. All people groups and governments fall subject before Yahweh and await his proclamations. Charles Hodge said, “God is described as controlling, with equal ease, things which are not and things which are. The actual and the possible are equally subject to his command. All things are present to his view, and everything is under his control.” Every tribe and nation are already under his rule, and fall under his judgement. No excuses are accepted, and the only pardon is found in the blood of Christ.
The rule of the Lord is absolute. His mercy and his justice are unmatchable. God has the ultimate ruling power, but he holds complete love for his elect. Because he wishes to call all nations to himself he lovingly and compassionately sends forth missionaries to reach the unreached and the lost. Each man in every tribe is responsible for his sins. The mercy of Christ spills across every land as his disciples labor to reach each people group. Every race and tribe was made in the image of God and he desires to be near the wonderous diversity he has created. This cannot and will not be done until the missionaries of Jesus take his mercy throughout the globe.
