'Call' in the Bible

Unto the church of God which is at Corinth, to them that are sanctified in Christ Jesus, called to be saints, with all that in every place call upon the name of Jesus Christ our Lord, both theirs and ours:

And I call upon you, brethren, through the name of our Lord Jesus Christ, that the same thing ye may all say, and there may not be divisions among you, and ye may be perfected in the same mind, and in the same judgment,

but to those who have received the Call, whether Jews or Greeks, Christ the power of God and the wisdom of God.

Think about the circumstances of your call, brothers and sisters. Not many were wise by human standards, not many were powerful, not many were born to a privileged position.

I call upon you, therefore, become ye followers of me;

and if any one of the unbelieving do call you, and ye wish to go, all that is set before you eat, nothing inquiring, because of the conscience;

and when He had given thanks, He broke it and said, “This is (represents) My body, which is [offered as a sacrifice] for you. Do this in [affectionate] remembrance of Me.”

In the same way, after supper He took the cup, saying, “This cup is the new covenant [ratified and established] in My blood; do this, as often as you drink it, in [affectionate] remembrance of Me.”

For example, if a bugle doesn't sound a clear call, who will get ready for battle?

in a moment, in the twinkling of an eye, at [the sound of] the last trumpet call. For a trumpet will sound, and the dead [who believed in Christ] will be raised imperishable, and we will be [completely] changed [wondrously transformed].
