"Peter said to Him, 'Lord, why can I not follow You now?'"
There are times when you can't understand why you cannot do what you want to do. When God brings a time of waiting, and appears to be unresponsive, don't fill it with busyness, just wait. The time of waiting may come to teach you the meaning of sanctification-to be set apart from sin and made holy- or it may come after the process of sanctification has begun to teach you what service means. Never run before God gives you His direction. If you have the slightest doubt, then He is not guiding. Whenever there is doubt-wait.
