在灵里（接上篇）
不仅如此，我们若要时时在灵里祷告，我们的意志必须是刚强的。一个意志像水母般的人不能祷告。祷告看起来容易，实际上并不容易。说话或者读书很容易，但是祷告不容易。这是祷告需要运用我们意志的原因。
基督徒必须是祷告的人。不祷告乃是罪；你若没有为别人、为圣徒、或为你的家人祷告，你就是在犯罪。然而，没有多少基督徒认为缺少祷告乃是罪。我们需要运用我们的意志，成为一班祷告的人。为着正当祷告生活的缘故，我们的心思必须是清明自守的，我们的情感必须受规律，我们的意志必须被加强；这样我们才能时时在灵里祷告。
为着祷告儆醒
保罗在十八节继续说，“并尽力坚持，在这事上儆醒，且为众圣徒祈求。”这指明我们需要为这祷告的生活儆醒，警戒。我们需要当心，免得我们应当专心祷告的时间被夺走了。为要实际的儆醒，教会中有许多人分出特定的时间祷告。
在祷告上儆醒，含示我们操练我们的意志，安定我们的心思，规正我们的情感，好有正确的祷告。在此需要相当多的操练，好使我们的心思、情感、和意志降服且顺从。因着许多人没有这样实行，他们的心思是背叛的。当他们对自己的心思说要安定下来，他们的心思反而变得更活跃。有的人情感是麻烦的。我们需要操练自己到一个地步，在结束一段很长的谈话时，还能立刻祷告。我们需要这样的操练，这含示在保罗所说，要儆醒祷告的话中。

Prayer as the Application of the Items of God’s Armor (3) — Eph. 6:18
Furthermore, if we would pray at every time in spirit, our will must be strong. A person with a will like a jellyfish cannot pray. It may seem that prayer is easy, but actually it is difficult. It is very easy to talk or read, but it is not easy to pray. This is the reason that prayer requires the exercise of our will.
A Christian must be a praying person. It is a sin not to pray. If you fail to pray for others, the saints or those in your family, you are sinning. However, not many Christians regard the lack of prayer as sin. We need to exercise our will to be people of prayer. For the sake of a proper prayer life, our mind must be sober, our emotion must be regulated, and our will must be strengthened. Then we shall be able to pray at every time in spirit.
Praying Watchfully
In verse 18 Paul goes on to speak of “watching unto this in all perseverance and petition concerning all the saints.” This indicates that we need to be watchful, on the alert, for this prayer life. We need to be on guard lest we be robbed of time that should be devoted to prayer. To be watchful in a practical way, many in the churches set aside specific times to pray.
To watch unto prayer implies that we exercise our will, calm our mind and regulate our emotion in order to pray properly. It takes a considerable amount of exercise to make our mind, emotion, and will submissive and obedient. Because many do not practice this, their mind is rebellious. When they tell the mind to calm down, it becomes all the more active. Others have trouble with the emotion. We need to be those who exercise ourselves to such a degree that as soon as we have finished a long conversation we are able to pray. The need for such an exercise is implied in Paul’s word about watching unto prayer.
