Verse 4 Does it say what I think it does? Yes and no

This is the #2 verse from the biblegateway list and #29 in the google 200. It is also highlighted in the 'Hands On' Bible.

Jeremiah 29:11
For I know the plans I have for you, declares the Lord, plans for welfare and not for evil, to give you a future and a hope.

Psalms 40:5
You have multiplied, O Lord my God,
your wondrous deeds and your thoughts toward us;
none can compare with you!
I will proclaim and tell of them,
yet they are more than can be told.

Isaiah 40:9-11
The Greatness of God
9 Go on up to a high mountain,
O Zion, herald of good news;
lift up your voice with strength,
O Jerusalem, herald of good news;
lift it up, fear not;
say to the cities of Judah,
“Behold your God!”
10 Behold, the Lord God comes with might,
and his arm rules for him;
behold, his reward is with him,
and his recompense before him.
11 He will tend his flock like a shepherd;
he will gather the lambs in his arms;
he will carry them in his bosom,
and gently lead those that are with young.

OK, does this verse mean that life will go well for us today, are the plans mentioned here for us, here and now. If you look at verses 4-14 you will see that this is a 'letter' from The Lord to His people going into captivity, and they wouldn't see the good of it for 70 years, and that they are not to listen to the prophets saying "peace,peace when there is no peace" like in chapter 8,14 and other places.
Yes God knows the plans He has for us, just as he did for the apostles. Yet, for Paul that meant

Acts 9:16
For I (the Lord) will show him (Paul) how much he must suffer for the sake of my name.”

Involving stonings, floggings, imprisonments and shipwrecks not to mention the other things he would recount in 2Corinthians 11.

His ultimate plan for us, is that like the Jews will be brought out of exile back to the promised land, so we will be restored to Him and in the words of Paul in his letter to the Colossians.

Colossians 1:11-14
May you be strengthened with all power, according to his glorious might, for all endurance and patience with joy, 12 giving thanks to the Father, who has qualified you to share in the inheritance of the saints in light. 13 He has delivered us from the domain of darkness and transferred us to the kingdom of his beloved Son, 14 in whom we have redemption, the forgiveness of sins.
