For no matter how many promises God has made, they are “Yes” in Christ. 
- from 2 Corinthians 1:20
 
God keeps his promises. And he makes a lot of them throughout the scriptures. A quick Google search reveals 371,000,000 websites that refer to God’s promises (all pulled up in .72 seconds). There’s a lot of interest in God’s promises.
 
Paul would have been writing to people who had a sense of the scope of God’s promises. They would have heard stories about God’s covenant commitment to his people, about God’s faithfulness even when his people were faithless, about the circuitous route God often took to fulfill his promises. 
 
Paul knew he was making a huge claim when he claimed that God’s promises are “Yes” is Christ.
 
This tells you something about how significant Paul considered Jesus to be. He is the reason we have access to God, confidence in our salvation, and power to seek the God’s kingdom. John Piper, reflecting on this passage, put it this way: “Every sinner who comes to God in Christ, with all his needs, finds God coming to him in Christ, with all his promises.”
 
In Christ, we see God’s persistent initiative. We aren’t left to our own devices. God follows through on his promises.
 
There’s a lot of nuance and complexity around this principle (which we’ll look at tomorrow). But today we want to invite you to pick a particular promise of God and ask “How does Christ fulfill this promise?”
 
You can pick any promise of God for this exercise (remember that aforementioned Google search?) or you can use one of these:

• “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.” – Jer. 29:11
•  “If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and will heal their land.” – 2 Chr. 7:14 
• “But you will receivepower when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.”– Acts 1:8
