Being a better person sounds simple. The problem is that we never really wrap our minds around what it meas to be a better person.
Here is a prayer to say so that we may start to get on the right road.
Our Father, may everything I do begin with Your Inspiration, continue with Your Help, and reach perfection under Your Guidance. With Your loving care guide me in my daily actions. Help me to persevere with love and sincerity. Teach me to judge wisely the things of earth and to love the things of Heaven. Keep me in Your presence and never let me be separated from You. Your Spirit made me Your child, confident to call You Father. Make Your Love the foundation of my life. Teach me to long for Heaven. May its promise and hope guide my way on earth until I reach eternal life with You. Amen
