Fulfill
Does it surprise you that the Bible almost never uses the word "fulfillment" in reference to a human's satisfaction in life? The Bible doesn't promise a fulfilling life. In the Bible, the word "fulfill" refers overwhelmingly to God's following through on his promises and intentions. God will always keep his promises. The plans he makes will come about. Our faithful God in control of all that happens in the universe, and his plans will overcome any obstacle.

Do you want to be fulfilled? Live in harmony with God's Word and his purposes. In practice, fulfillment is sometimes the exact opposite of what the world considers smart or savvy. Jesus said, "Whoever wants to save his life will lose it, but whoever loses his life for  me will save it" (Luke 9:24). God wants us to lose ourselves in him and his purposes; in return, he promises a life beyond what we can even imagine (see Ephesians 3:14-21). It's a paradox worth living.

God has always fulfilled the prophecies in his Word, and he will continue to do so.
