Prayer that I can identify with

Dear God, Sometimes I feel like I have poured myself into something or someone, and worked and fought for a cause, only to see little fruits for my labors. It all seemed in vain. But I know that You can work in all of that to fulfull a greater purpose. Please, don't let the labor of my heart and hands be in vain. I pray that all I do would be as unto You and for a good purpose and eternal value. Please bless the works of my heart and hands for Your glory. Please empower me with wisdom and insight throughYour Holy Spirit. Please guide me every step and every day, to have a part in reaching this world for You and ministering to those I love. In Jesus' name, amen. - from Ephesian four ministry
