As moms, we do not have the power to make a heart change in our daughters, but each day we are given the opportunity to point them back to Jesus.
Let her see you take all things in moderation. Choose her over online time, unnecessary commitments. Guard your temper. Be mindful to take care of your body, a temple of the Holy Spirit.
All of this can only come from the Fruit of the Spirit. Galatians 5:22-23:
But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law.
Let her see that there is no law against such things. And keep pointing her to Jesus.
