Jeremiah 29:11

For I know the thoughts that I think toward you, says the LORD, thoughts of peace and not of evil, to give you a future and a hope.—Jeremiah 29:11

The exiles in Babylon did not know or remember that God thought about them...that His thoughts were “toward” them for their good...peace and not evil...to give them a future and a hope.  God wrote them a letter through Jeremiah to remind them. God has done the same for us...He has given us His word.  As a believer, God’s thoughts toward me are good, but like the exiles, I forget. 

Your thoughts toward us cannot be recounted to You in order; if I would declare and speak of them, they are more than can be numbered—Ps 40

How precious also are Your thoughts to me, O God!

How great is the sum of them! If I should count them, they would be more in number than the sand; When I awake, I am still with You.—Ps 139:17-18

No matter where we find ourselves...no matter the trials we face here...He is with us to help us.  Our future is secured.  Eternal life in heaven is ours.  He gave His life to assure it. We have a hopeful end. 

In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise, who is the guarantee of our inheritance until the redemption of the purchased possession, to the praise of His glory.—Ephesians 1:13-14
