Matthew 20:13-14 But he answered one of them and said, ‘Friend, I am doing you no wrong. Did you not agree with me for a denarius?  Take what is yours and go your way. I wish to give to this last man the same as to you.”
These two verses show how selfish humans really are. We need to work on our hearts being in the right place. Ask the Holy Spirit to give you a heart of joy for others. Pray: Father, I pray you would soften my heart. Allow me to be happy for those who have done great things. Take away the jealousy and pride in my heart. Amen.
