Pray without ceasing. Some think that literally means to pray all day long, but I think you just need to be in a continual state of worship to Him. It doesn't have to be verbal or even thought. It could be sitting under the shade of a tree. It could be painting. It could be running. It could be being with your besties. I think it just needs to be whatever makes you feel that you're glorifying Him and what makes you feel closest to your Maker.
