This is what the LORD says: “When seventy years are completed for Babylon, I will come to you and fulfill my gracious promise to bring you back to this place. For I know the plans I have for you,” declares the LORD, “plans to prosper you and not to harm you, plans to give you hope and a future.” (Jeremiah 29:10–11, 29:11).
He [Jeremiah] has sent this message to us in Babylon: “It will be a long time. Therefore, build houses and settle down; plant gardens and eat what they produce.” (Jeremiah 29:27–28, NIV 1984).
“Do not let your hearts be troubled. Trust in God; trust also in me. In my Father’s house are many rooms; if it were not so, I would have told you. I am going there to prepare a place for you. And if I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am.” (John 14:1–3, NIV 1984).
He [Jesus] said to them: “It is not for you to know the times or dates the Father has set by his own authority. But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.” (Acts 1:7–8, NIV 1984). “Until the full number of the Gentiles has come in.” (Romans 11:25, NIV 1984).
You know with all your heart and soul that not one of all the good promises the LORD your God gave you has failed. Every promise has been fulfilled; not one has failed. (Joshua 23:14, NIV 1984).
My Musings – The harmony between the Old and the New should not be surprising when you realize they had the same author. We can look back to the promises that were fulfilled (“[once] seventy years [were] completed for Babylon“), as affirming that the promises yet to be fulfilled will be fulfilled – in their time (“until the full number of the Gentiles [have] come in“). No promise of His has failed yet, and none ever will.
My Advice – Don’t grow discouraged by the things you see going on in the world today. Things will work out just as He promised -“I will come back and take you to be with me.” Just be patient, and “do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, not wanting anyone to perish, but everyone to come to repentance. But the day of the Lord will come…” (2 Pe 3:8–10, NIV 1984).
