Robert Gotcher on Heart, Mind and Soul:
The best sign of being stuck on the lower levels is ingratitude. If you are more likely to spontaneously complain that God is not being generous to you or responsive to your obvious needs rather than spontaneously giving thanks for all the generous and wonderful gifts God is showering upon you daily, hourly, by the minute, then you are stuck on level one or two. If the people God puts in your life daily seem to you to be either obstacles to your happiness or at least irrelevant, then you are seeking ego gratification. God never withholds opportunities for pursuing happiness on the third and fourth level (service and spiritual growth respectively). We are never at a loss for opportunities for service nor for spiritual growth and deepening our relationship with the Lord.
