Psalm 118:6 “The Lord is for me, so I will have no fear. What can mere people do to me?”
When I am facing a challenge where other people are involved, all I have to remember is that because I am in Christ, God is always involved in the situations I face. And whether it is something I must learn from, or overcome to get stronger, the attitude I must have is that God is doing a work IN me and He is working out His plan in my life.
Whatever the other person may be doing or not doing is inconsequential, it is to God they will answer. I must focus on myself and what God is doing in my life. And when I remember that through it all, God loves me, I will have nothing to fear.
