'Call' in the Bible

‘I know your deeds and your toil, and your patient endurance, and that you cannot tolerate those who are evil, and have tested and critically appraised those who call themselves apostles (special messengers, personally chosen representatives, of Christ), and [in fact] are not, and have found them to be liars and impostors;

So remember and take to heart the lessons you have received and heard. Keep and obey them, and repent [change your sinful way of thinking, and demonstrate your repentance with new behavior that proves a conscious decision to turn away from sin]. So then, if you do not wake up, I will come like a thief, and you will not know at what hour I will come to you.

Then I saw as the Lamb (Christ) broke one of the seven seals [of the scroll initiating the judgments], and I heard one of the four living creatures call out as with a voice of thunder, “Come.”

When He (the Lamb) broke the second seal, I heard the second living creature call out, “Come.”

When He (the Lamb) broke open the third seal, I heard the third living creature call out, “Come.” I looked, and behold, a black horse [of famine]; and the rider had in his hand a pair of scales (a balance).

When He (the Lamb) broke open the fourth seal, I heard the voice of the fourth living creature call out, “Come.”

but when it is time for the trumpet call of the seventh angel, when he is about to sound, then the mystery of God [that is, His hidden purpose and plan] is finished, as He announced the gospel to His servants the prophets.

If anyone is destined for captivity, he will go into captivity; if anyone kills with a sword, he must be killed with a sword. Here is [the call for] the patient endurance and the faithfulness of the saints [which is seen in the response of God’s people to difficult times].

Here is wisdom. Let the person who has enough insight calculate the number of the beast, for it is the [imperfect] number of a man; and his number is six hundred and sixty-six.

Here is [encouragement for] the steadfast endurance of the saints (God’s people), those who habitually keep God’s commandments and their faith in Jesus.
