Do you take time to pray daily?  I find that many people today think they have no time to pray and yet they say I am so tried and weary.  It amazes me to think that most Christian are so blinded from the power that prayer brings.  Why?
If Satan cannot distract you with worldliness, He will overwhelm you with weariness. Indeed, how easy it is to wear ourselves out; even good works done without recharging ourselves in God can drain us of life and energy.

Daniel speaks of a time at the end of the age when the enemy will attempt to “wear down the saints of the Highest One” (Dan. 7:25). God never intended for us to do His will without His presence. The power to accomplish God’s purpose comes from prayer and intimacy with Christ. It is here, closed in with God, where we find an ever-replenishing flow of spiritual virtue.
