Why do we make the right choices?
We don't just make our choices because it is simply "the right thing to do" or "it's what we were taught." While those option are definitely true, we choose to live and obey God in our lives regardless of what those without Him do around us because of even a greater and deeper reason. The choices that we make come down to one thing--loving God--truly loving God above all else that this world tries to offer us.
When we love God--we make different choices than world around us. And we hopefully keep making those choices no matter how God leads us down the path and regardless of what or does not be allowed into our lives.
Mark 12:30 "Love the Lord your God with all your heart and with all of your soul and with all of your mind and with all of your strength."
May you be strengthened by His Spirit to love Him with all that you are today.
