The moment you make the commitment to the Lord to drastically change your prayer life, you will be hit with obstacles. It never fails. Some are self-inflicted (by accident or intentional). Some of them are just life. Things happen. Some are caused by the enemy. And others are test from God to see if we are going to be faithful. But, the cause of the obstacles does not matter at all. (Re-read the previous sentence as many times as necessary until it sinks in and becomes truth in your heart and mind.)
Instead, what matters is what you do with those obstacles.
Are you going to get upset with God--or just upset in general?
Or are you going to dig in an pray even harder, far longer, and grow determined in prayer? That is the question. This is what sets apart the prayer-giveuppers and the prayer-nevergiveuppers.
Be a prayer warrior! Dig in. Never give-up. Never. There are souls at stake.
