Is Jesus Christ Lord of heaven and earth?
Yes. He ascended into heaven and is seated at the right hand of the Father. He will come again in glory to judge the living and the dead, and His kingdom will have no end.
Catechism for the Global Methodist Church, question 15
1:33He will reign over the house of Jacob forever, and his kingdom will have no end." 24:51And while he was blessing them, he parted from them and was carried up into heaven.
22The Father judges no one, but has given all judgment to the Son. 23This is so that all may honor the Son just as they honor the Father. The one who does not honor the Son does not honor the Father who sent him. 24Truly, truly, I say to you that the one who hears my word and believes him who sent me has eternal life and does not come into judgment, but has passed from death to life. 25Truly, truly, I say to you that an hour is coming, and now is, when the dead will hear the voice of the Son of God, and those who hear will live. 26For just as the Father has life in himself, so also he has granted the Son to have life in himself. 27And he has given him authority to execute judgment, because he is the Son of Man. 28Do not marvel at this, because an hour is coming in which all who are in the tombs will hear his voice. 29And those who have done good will come out to the resurrection of life, and those who have done evil to the resurrection of judgment.
9And after he had said these things, while they were watching, he was lifted up, and a cloud took him out of their sight. 10And as they were gazing into heaven while he was going, behold, two men in white clothing stood by them. 11They also said, "Men of Galilee, why do you stand looking into heaven? This Jesus, who was taken up from you into heaven, will come in the same way you saw him going into heaven."
42He ordered us to preach to the people and to testify that this one is the one having been determined by God as judge of living and dead.
34Who is to condemn? Christ is the one who died, more than that, who was raised, who is at the right hand of God, who indeed intercedes for us.
10For we must all appear before the judgment seat of Christ, so that each one may receive what he has done in the body, whether good or evil.
9Therefore God also exalted him and gave him the name that is above every name. 10So that at the name of Jesus every knee should bend, in heaven and on earth and under the earth. 11And every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
11For in this way entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be richly supplied to you.
15And the seventh angel sounded a trumpet, and great voices arose in heaven, saying, "The kingdom of the world has become the kingdom of our Lord and of his Christ, and he will reign to the ages of the ages."
Jesus Christ reigns now, and he will return. The creed confesses that he "ascended into heaven and is seated at the right hand of the Father. He will come again in glory to judge the living and the dead, and his kingdom will have no end." Article II of the Confession of Faith teaches the same: he "ascended into heaven to be with the Father, from whence he shall return," and "by him all men will be judged." Article III of the Articles of Religion says he "sitteth until he return to judge all men at the last day."
Ascended into heaven. The apostles watched it happen. Luke records that "while he was blessing them, he parted from them and was carried up into heaven" (Luke 24:51), and in Acts "a cloud took him out of their sight" (Acts 1:9). Seated at the right hand of the Father. To sit there is to share the Father's rule, and Paul says the one who sits there "indeed intercedes for us" (Romans 8:34). Because God "exalted him and gave him the name that is above every name," the day is coming when "every tongue should confess that Jesus Christ is Lord, to the glory of God the Father" (Philippians 2:9, 11).
He will come again in glory to judge. The same Lord who went up will come down again. The two men in white told the disciples that "this Jesus, who was taken up from you into heaven, will come in the same way you saw him going into heaven" (Acts 1:11). Jesus himself taught that the Father "has given all judgment to the Son" (John 5:22), and Peter preached him as "the one having been determined by God as judge of living and dead" (Acts 10:42). His kingdom will have no end. Gabriel promised as much to Mary (Luke 1:33), and heaven sings it at the seventh trumpet: "he will reign to the ages of the ages" (Revelation 11:15).
A Methodist confesses this Lord every time the creed is said and every time "Jesus is Lord" is spoken at baptism. The believer already lives under a king whose reign is settled and whose return is certain (Acts 1:11). Peter promises that for those who hold to him, "entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be richly supplied" (2 Peter 1:11).
