There are many Primary songs I like, but there are a few I'd change the words to
"I belong to the church of....." No, the church does not own me. I choose it and own it as mine to work in and serve in. I belong to Christ.
"There's a right way to live and be happy..." Actually, there's a right way to live and find Christ's peace. Sorrow comes to all of us in this life.
"It is choosing the right every day..." and also repenting and turning to the Lord when you mess up all the time too. You should not automatically assume that success, peace or happiness is only achieved if you never choose the wrong. Repentance is every day too.
"Follow the prophet...he knows the way...." Well, it's way more complicated than that. Follow Jesus, listen to prophets, respond to what the Holy Spirit tells you is light and truth, forgive people called as prophets their weaknesses and appreciate their strengths, continue in faith. Yup. Way more complicated.
"Scripture power, the power to win...." Win? Really? This life is not a competition. Time in the scriptures increases discernment of what is wise and good and needful in life and in order to become a better disciple. But it does not give you "power to win". It actually decreases your interest in "winning".
Any Primary lyrics you'd change?
