According to The Cambridge Dictionary, seek means “to try to find or get something, particularly something that is not a physical object.” https://dictionary.cambridge.org/dictionary/english/seek

In order to find God’s will for your life, you have to look for it, not just proclaim that you know it and you’re already following it. When you sincerely try to find His will for you, then He will show you the path that you should be taking. Seeking God’s will first before taking a path is the way to do things to avoid a lot of heartache and trouble. You will still have trouble because we live in a fallen world, but at least you will know that you are on the path that God has led you to and He is walking beside you on it. God walks with us regardless of our choices to follow our own will or His, but we should know that His will is what is best for us and in the end will bring us the greatest joy. Seek and follow.
