He that spared not His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things? – Romans 8:32

The soul grows rich in love to God when she rests on the bosom of divine lovingkindness. You, who are tossed about with doubts and fears as to whether you are now accepted or shall persevere to the end, you can scarcely guess the ardours of heart which inflame those saints who have learned to cast themselves wholly upon Jesus and know beyond a doubt His love immutable. Whether I sink or swim, I have no hope but in Christ, my life, my all.

“I know that safe with Him remains,
Protected by His power,
What I’ve committed to His hands
Till the decisive hour:”

And in proportion as I am thus scripturally confident, and rest in my Lord, will my love to Him engross all my heart, and consecrate my life to the Redeemer’s glory.

Beloved, I desire to make this very clear, that to feel love to God we must tread along the road of faith. Truly, this is not a hard or perilous way but one prepared by infinite wisdom. It is a road suitable for sinners, and indeed saints must come that way too. If thou wouldst love God, do not look within thee to see whether this grace or that be as it ought to be, but look to thy God, and read His eternal love, His boundless love, His costly love, which gave Christ for thee; then shall thy love drink in fresh life and vigour. ~ C.H. Spurgeon
