About Jonathan Caswell

Poet, author, servant of God the Heavenly father and the Lord Jesus Christ...working out his salvation with fear and trembling. - Not trusting in his own deeds, but depending totally upon the finished sacrificial work of Jesus Christ to be, by God's reckoning, a new creature, clothed in Christ's righteousness...which mortal humankind can never attain by their own weak efforts, apart from faith in Christ's work on our behalf. - College-educated, yet wise enough to see that what a man does will not be his ultimate identity nor affect how God sees him or her. - Called by God to do a very difficult thing...apart from God's grace, mercy and strength...to love the sinner (which we all--by nature--are) but hate the sin, which is only paid through Christ, God's Son, - My own God-given gift is that of being a Poet..showing that in all parts of life...God has a loving part in it...as hard as that is to always understand or perceive...given life's realities! Come join me on my journey of discovery?.
