The Psalmist said, “Thy word i have treasured in my heart, that i may not sin against Thee” (Ps. 199:11) Without knowledge, we are defenseless and vulnerable.
Knowing God’s truth by study and application enables us to say no to sin and yes to righteousness. Anyone who puts his faith in Jesus Christ but who does not keep God’s Word constantly at the forefront of his mind will find himself entrapped in sin again and again. For a Christian neglecting the Word is spiritual starvation.
