“I discovered a man whose understanding of God influenced the way he interacted with others, shaped his desires and prayers, and handled everyday situations.” - James Spencer
Jesus came, ministered, suffered, died, and rose in 3.5 years. So the church will teach, demonstrate, suffer, die and be resurrected at the time appointed by God.
Jesus the only Son of God, came to earth, suffered, died, and rose again defeating Satan and evil. He is coming again and He will rule and reign forever.
As Christians we are not responsible for fixing the world. The world is so broken only God can fix it. What we are responsible for as Christians is to live so close to Jesus that He and His ways are formed in us. This changes our hearts and our world at the same time.
