In Matthew 20, Jesus said to his disciples, "Whoever wishes to be great among you shall be your servant; whoever wishes to be first among you shall be your slave." Again, in Matthew 23, he spoke to the crowds and to the disciples, "The greatest among you must be your servant. Whoever exalts himself will be humbled; but whoever humbles himself will be exalted." Here's one greatest teaching from Jesus. Humility and willingness to serve go hand in hand. You can be a great speaker trying to convert others, but if you lack humility, you still remain a hypocrite. We now have the secret of attaining freedom and being exalted by the Lord.
