Definition: For the promise, that he should be the heir of the world, [was] not to Abraham, or to his seed, through the law, but through the righteousness of faith.

Explanation: Okay, let’s break down this passage from Romans 4:13. It's a really important and fascinating idea about God’s plan for salvation! Here’s what it means in simpler terms: Basically, God isn’t giving a promise to Abraham or his descendants through strict rules or laws. Instead, He chose a specific way – faith – to give someone the opportunity to be with Him. Let's unpack that a little more: “The promise…” - This refers to a promise made by God to Abraham, who was an old man and a very important figure in Jewish history. It’s a promise about how God will deal with his descendants. “…that he should be the heir of the world…” – This is a fancy way of saying “He will inherit everything.” This refers to everything – all the good things, the blessings, and ultimately, the ultimate kingdom of God. "...[was] not to Abraham, or to his seed..." - Now, this is key! It’s not about Abraham inheriting the world through his descendants. It’s about a different kind of inheritance – through faith. "...through the righteousness of faith." - This is the most important part. “Righteousness of faith” means that God doesn't earn this inheritance with good deeds or religious practices. Instead, it comes from believing in Jesus Christ and accepting Him as our Savior. So, what does this mean for us? It means that God’s plan for salvation is based on trusting in Jesus. We don't have to earn a place in Heaven with our own efforts. Instead, we receive it because of the sacrifice of Jesus Christ who died for us. Our faith in Him is enough to be included in the “inheritance” – that’s the eternal life and relationship with God. Think of it like this: Imagine you're a farmer planting seeds. You don’t earn the land, you just plant the seeds! God chose Abraham as a special example, showing us how we can receive the rewards (eternal life) through faith in Jesus Christ. --- Do you want me to explain any of these concepts further? For example: We could delve deeper into the significance of "faith." I could give you an analogy or a story to help illustrate the idea?
