Which in his times he shall shew, who is the blessed and only Potentate, the King of kings, and Lord of lords;
In his times, х kairois (G2540) idiois (G2398)] - 'His own (fitting) seasons' (Acts 1:7). The plural implies successive stages in manifesting the kingdom of God, each having its own appropriate time; the regulating principle and knowledge of which rest with the Father (1 Timothy 2:6; 2 Timothy 1:9; Titus 1:3; Hebrews 1:1).
He shall show - display as a mighty "sign" to men (Matthew 16:1) х deixei (G1166)], appropriate to His "APPEARING" [epiphaneia], which is stronger than His 'coming,' and implies its visibility (cf. Acts 3:20): "He" is the Father (1 Timothy 6:16).
Blessed - so about to be the source of blessing to His people at Christ's appearing, whence flows their "blessed hope" (Titus 2:13; 1 Timothy 1:11).
Only (John 17:3; Romans 16:27; Revelation 15:4).
King of kings - elsewhere applied also to Jesus (Revelation 1:5; Revelation 17:14; Revelation 19:16).
