No matter how young or old you are this is a great principle to learn about. In a nutshell the 5 Love Languages are Words of Affirmation, Quality Time, Receiving Gifts, Acts of Service & Physical Touch. You may already be able to guess what your love language is but I do recommend reading the book as you may find that your love language is not what you thought it was. Most importantly you may receive love in one language but need to speak another language to give love to someone.
I have used the principle of love languages in my marriage, in my friendships, in my relationship with my children & in my relationship with God! It might sound silly to you but I try to tell God how I love Him in all sorts of different ways 🙂 God IS love! Eric preached on this recently & it is powerful when you think about it. God doesn’t have love for us He IS love. If God is love then it makes sense that us learning about love & how to love is really important.
I highly recommend this book as a great starting point to learning about all the different ways love is expressed & received. If we all simply grasped & used love this world would be a much nicer place. Check out the 5 Love Languages website too for all sorts of resources.
