“I urge that supplications, prayers, intercessions, and thanksgivings be made for all people, for kings and all who are in high positions…” (1 Timothy 1:1-2)
The benefit of praying for "all people" leads to peace...
“…so that we may lead a peaceful and quiet life, godly and dignified in every way…and this is pleasing in the sight of God our Savior…” (1 Timothy 1:2-3)
When will this peace come to all people? When "all people" are saved and have come to a realization of the truth...
“…God our Savior, who wills all people to be saved and to come to the knowledge of the truth.” (1 Timothy 1:4)
And the truth is...
“…that there is one God, and there is one mediator between God and humanity, the man Christ Jesus, who gave himself as a ransom for ALL PEOPLE.” (1 Timothy 2:5-7)
God is the hope for humanity - not the religious and political leaders among us. And God has determined to be the Savior of "all people"...
“…we have our hope set on the living God, who is the Savior of all people, especially of those who believe.” (4:10)
One prayer that is sure to be answered is the prayer for all people to be saved and come to a knowledge of this truth. It is the "eternal purpose" of God that humanity be unified into the body of Christ, the true church. It is guaranteed by the grace of God and it is a gift. It is accomplished "in Christ Jesus our Lord".
"...the Gentiles are fellow heirs and fellow members of the body, and fellow partakers of the promise in Christ Jesus through the gospel...This was in accordance with the eternal purpose which He carried out in Christ Jesus our Lord..." ..."There is one body and one Spirit, just as also you were called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all people who is over all and through all and in all. To each one of us this grace was given according to the measure of Christ’s gift." (Ephesians 3:1-9; 4:4-6)
