Prayer For Lack Of Concentration

Dear Heavenly Father, I find that my mind too often starts to wander when I am needing to concentrate on the issue at hand. I know that the Bible encourages us to be alert and attentive, knowing that lapses in concentration can be quite serious and I ask that You would help me to cope with this issue and teach me how to keep my mind focussed on the job that needs to be done.
Help me Lord, to be sober and vigilant, just like the Bible says, knowing that the enemy is like a roaring lion who is seeking to devour and harm those that are Your children. You see Lord, I do not want this inability to concentrate to become my downfall in this area.
Lord, You have told us to cast all our cares and concerns on You, and this is becoming a major worry for me. Keep me I pray from becoming distracted and help me to develop the ability to really concentrate at work and during my study times, and also during my prayer sessions. Thank You, Lord, for listening and answering my petition. In Jesus' name,
