Our attitude toward others reveals our genuine attitude toward God.
Your attitude toward the word of God is your attitude toward Jesus (Ps 37:4).
The true power of love is found in selfless attitudes and actions that seek the best for another person without expecting anything in return. When we act in that way, the feeling of love follows close behind.
Happiness is about what happens to you; and, to an extent, it's dependent on your circumstances, your behaviors, and your attitudes. But the joy of Christ is much, much bigger. The joy of Christ is about relationship with a person. It's something you have access to, but it's also something you must choose. Christian joy shows up not only in the happy times but also in times of trial and discouragement.
To avoid the trap of the Pharisees, we've got to guard the interconnection between our thoughts and our attitudes.
