“But God commendeth His love toward us, in that, while we were yet sinners, Christ died for us.” Romans 5:8 (KJB)
There are several “But God” statements throughout the New Testament, and the apostle Paul was quite good at using them.
“But God…” even while we were still His enemies sent His Son to die for us. How unhuman that is; how so much GOD it is.
“Greater love hath no man than this, that a man lay down his life for his friends.” John 15:13
“But God” in the Person of His Son Jesus Christ, went to the cross and died even for those who condemned Him to die; He died for those who falsely accused Him; for those who beat Him so cruelly; for those who drove the nails in His hands and feet; for the one who thrust the spear into His side. Some of them believed, and were redeemed.
How much greater love is that.
“But God” while we were yet sinners poured out His wrath in its fullness upon His only begotten Son, who had became our sin (2 Corinthians 5:21), and gives to all who will believe His holiness, His righteousness, and declares us Just.
“But God…” has clearly demonstrated His hatred for our sin; and His love for us by way of the cross of Jesus Christ. He died, was buried, and was raised to life. He is the only way, the only truth, and the only life; the only way to the Father.
