The God we serve does not want us to wallow in self-pity. Thus, it makes sense for us to remain faithful that God will carry us through. Jesus died so we could have life and have it more abundantly (John 10:10), not so we can wallow in a lifetime of grief.
So whatever life throws you, just know this: Having a Positive Attitude in Spite of it All will help get you to the finish line of problems and assist you with staying in a positive, thankful, faithful posture with the Lord Jesus Christ. He will never leave you nor forsake you.
