Sometimes we feel as if we don't understand ourselves—what we want, how we feel, what's wrong with us, or what we should do about it. But God's understanding has no limit, and therefore he understands us fully. If you feel troubled and don't understand yourself, remember that God understands you perfectly. Take your mind off yourself and focus on God. Seek to become more and more like him. The more you learn about God and his ways, the better you will understand yourself.
Psalms 147:10-11
We may spend a lot of effort trying to sharpen our skills or become physically fit. There is nothing wrong with doing so, and, in fact, our gifts can be used to glorify God. But when we use our gifts with no regard for God, they are indeed worth little. It is our honor and trust that God desires. When he has those, then he will use our gifts and strengths in ways far greater than we can imagine.
Psalms 147:19-20
The nation of Israel (the descendants of Jacob) was special to God because to its people God brought his laws, and through its people he sent his Son, Jesus Christ. Now any individual who follows God is just as special to him. In fact, the Bible says that the real nation of Israel is not a specific people or geographic place but the community of all who believe in and obey God (see Gal 3:28-29).
