Continue in prayer, and watch in the same with thanksgiving. Colossians 4:2 (AKJV)
Not only should we be diligent in prayer but also watch or be alert in it. In prayer we are first and foremost communicating with God. We speak to Him and He also speaks to us. When you are communicating with someone you talk to them and
they also talk to you. There’s a listening part in prayer. It’s not all about you doing all the talking or asking. When in prayer we ought to go the whole route of also listening to what God is saying in response. This is what the watching or keep checking part in prayer is all about. Don’t pray only but also keep checking because the answer may have already been given.
We keep checking by being still and listening to our hearts where God speaks and answers us.
There could also have been sent further instructions like “now instead of praying give thanks, praise, rejoice or be quiet”.
We also keep checking by paying attention to what’s happening around us because God can give us clues or signs in seemingly insignificant things
