Where do we get the faith that is required for salvation? Ephesians 2:8 answers: "For by grace you have been saved through faith, and that not of yourselves; it is the gift of God." We cannot work it up—that would be our effort (Isaiah 64:6).
Consider when God first started working with us. One year we were clueless, the next year things were making sense. We read the Bible and understood it, but more importantly, we believed it.
Where did that belief come from? It was, as Ephesians 2:8 says, a gift from God. The real miracle is not that we understood, but rather that we now believed those words we understood. And this happened only because God made it possible.
What was the evidence that we believed those words? We began living by them. Our new works and actions were the evidence of our faith: keeping the Sabbath, tithing, eating habits, etc.
Just like Abraham, our actions showed our desire to begin a right relationship with God motivated by His gift of faith. "Don't you remember that our ancestor Abraham was declared right with God because of what he did when he offered his son Isaac on the altar? You see, he was trusting God so much that he was willing to do whatever God told him to do. His faith was made complete by what he did—by his actions" (James 2:21-22, New Living Translation).
To complete our faith, are we willing to believe and do whatever God tells us? Consider those first experiences as we began to believe. We faced family pressure, work pressure, peer pressure, etc., to obey what we now believed. What evidence did we have to back up our actions? All we had were God's words. Armed with only those words, we willingly faced any opposition to act on what God commands. Just like Abraham, it was our faith in those words that encouraged us to obey and begin our journey, not knowing where we were going (Hebrews 11:8).
At our baptism, could we have predicted all the twists and turns our lives have taken since? Just like Israel's journey after baptism in the Red Sea, God has taken us in a zigzag route across this wilderness we call life. What was our evidence of things not seen? Only the words of God. That was the only evidence we had then, and it is the only sure evidence we have now.
As we deal with our trials, do we remember that first love? Do we remember the challenges we were willing to confront with only the words of God as our evidence? It is no different today. Will we believe God or what we can see? God needs to find out just as He did with Abraham—to "know" we will obey, no matter what, until the end (Matthew 10:22).
To test our faith, God's pattern is to bring us to a point—a brick wall or a Red Sea—that seemingly allows no escape. That is where He can find out what is truly in our hearts—hearts of belief or evil unbelief (Hebrews 3:12). Will we believe Him or our eyes?
