Do you know what is meant by this bibical saying?

1 Peter 1:8-9 (The Message)

8-9You never saw him, yet you love him. You still don't see him, yet you trust him—with laughter and singing. Because you kept on believing, you'll get what you're looking forward to: total salvation.

1 Peter 1:8-9 (Amplified Bible)

8Without having seen Him, you love Him; though you do not [even] now see Him, you believe in Him and exult and thrill with inexpressible and glorious (triumphant, heavenly) joy. 9[At the same time] you receive the result (outcome, consummation) of your faith, the salvation of your souls.

1 Peter 1:8-9 (New International Version)

8Though you have not seen him, you love him; and even though you do not see him now, you believe in him and are filled with an inexpressible and glorious joy, 9for you are receiving the goal of your faith, the salvation of your souls.

And- yes! Absolutely! all Christians should know this feeling (although- 'feeling' is not the best word) I would use 'state of mind' or 'state of being' (the word 'feeling' has too much present tense emotion associated with it to describe joy in all it's forms)

For me- the joy is always there (in my heart) because as a Christian- I have security (love, forgiveness, peace & salvation- all great things to be joyful about) but at times, the joy 'feels' closer to the surface and more tangible especially when I think specifically about any of these gifts or contemplate Jesus' sacrifice for me!

When the New Testament speaks of joy, it translates a word meaning positive outlook. I can describe it to an extent, but not fully, hence unspeakable. For me, it is the feeling of peace and contentment I have, because I know that God is looking after every aspect of my life, leaving me with nothing to worry about except getting on with it. I don't need to think about myself, that leaves me free to think about the needs of those around me. Hopefully, help them experience joy.

"Joy" is not the same as happiness. Have you ever had your "giggle box" explode with uncontrollable laughter? but did not really understand what started it? That is similar to "unspeakable joy" -- your heart would be overflowing with that "uncontrollable laughter" inside!

christians do

it is joy that comes from god that we can not describe adequately with words

we are full of the glory that comes from god

The day will come when the mystical generation of Jesus by the Supreme Being in the womb of a virgin, will be classed with the fable of the generation of Minerva in the brain of Jupiter.
