As Christians, we enjoy a certain amount of favor...and many blessings from God. We forget, easily, that his blessings are conditional on our behavior.
"And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people." (Ephesians 6:18)
"Pray continually." (1 Thessalonians 5:17)
"Is anyone among you in trouble? Let them pray." (James 5:13)
"Be joyful in hope, patient in affliction, faithful in prayer." (Romans 12:12)
"Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God." (Philippians 4:6)
When God says to stop praying:
When there’s unrepentant sin. Joshua 7
When It’s time for action. Exodus 14
When you’re doing so with selfish motives. Luke 10
Bottom line: Don’t get too comfy on the couch. The ONE THING worth being concerned about is relationship with your heavenly father, through Jesus Christ. If that’s right, the rest will be worked out.
