Judas never planned to betray Jesus but it happened because he had to,if he hadn't betrayed him he wouldn't have died for us. He could have delayed the process, if Peter hadn't denied Jesus he would have thought he was perfect,a saint of loyalty.
But some things happen to us because they just have to happen in order to push us to greater heights and to teach us things that we wouldn't have ever known,sometimes our destiny pointers come from the betrayals we face. It's some peoples role in your life to betray you in order to catapult you for greatness. For every pain there is gain,never lose hope. Trust the process of you becoming the better you waiting to become. No matter how much it hurts,hold on. Greatness is never easy to attain,it's from endurance and strength built through struggles.
