Commandments are ways for us to learn doctrines by living them. Keep yourself in a growth mindset by looking for new things to learn and stop beating yourself up about things you don't understand yet.
We are blessed for living commandments, but not always in predictable ways. When we don't get the blessing we were counting on, we may blame ourselves or Heavenly Father. Using commandments to connect with Heavenly Father, however, will always bring us the blessings of His presence and we will have joy and peace regardless of other circumstances.
Commandments will not keep us from having difficulties in life, but they can teach us how to care for and protect one another.
Both Judas and Peter wanted Jesus to establish a political kingdom for Israel and overthrow the Romans, but only one followed God's plan.
Submissive unity with God is not an erasure of ourselves, it is a part of finding and strengthening ourselves.
To be united with God is possible. Seek His will and He will teach it to you, and to see His will is to love it as your own.
