This is a great prayer for more Gospel-centredness in your thoughts and affections. Pray and see what happens!
THE GOSPEL WAY
BLESSED LORD JESUS,
No human mind could conceive or invent the Gospel.
Acting in eternal grace, thou art both its messenger and its message,
lived out on earth through infinite compassion,
applying thy life to insult, injury, death,
that I might be redeemed, ransomed, freed.
Blessed be thou, O Father, for contriving this way,
Eternal thanks to thee, O Holy Spirit,
for applying this way to my heart.
Glorious Trinity, impress the Gospel on my soul,
until its virtue diffuses every faculty;
Let it be heard, acknowledged, professed, felt.
