Whatever dims thy sense of truth Or stains thy purity, Though light as breath of summer air, Count it as sin to thee. Let not the world thy God dethrone Or from His smile divide; And count compared with heavenly wealth, As dross all things beside. Dim not the crystal of thy soul By sin’s destroying breath: There lurks beneath the siren smile Dark treachery and death. Preserve the tablet of thy thoughts From every blemish free, For our Redeemer’s lowly faith Its temple makes with thee. And pray of God, that grace be given To tread time’s narrow way: How dark soever it may seem, It leads to cloudless day.
