I have not seen a scientific study on the subject, but it seems to me that people’s expectations and attitude have an effect on how things work for them. When people tend to expect things will work out, and are optimistic, it seems like things tend to go well for them. On the other hand, people that tend to see and talk about the negative results, and tend to expect that things will not work out, tend to get what they expect.
The Bible appears to allude to this in a couple passages. Proverbs 11:27 says, “Whoever seeks good finds favor, but evil comes to one who searches for it.” Though used in a little different context, Galatians 6:7 says, “Do not be deceived: God cannot be mocked. A man reaps what he sows.”
As Christians, we know God loves us, and is watching over us. We also know that we are saved for eternity. With this foundation, how can we not be optimistic and move forward expecting good things.
Dear Lord, you have offered peace to those who follow you, and we should have joy knowing that you care for us. Help us move forward therefore, seeking good as Proverbs says and expect the favor you promise. In Jesus’ name we pray. Amen.
