Romans 3:10 As it is written, There is none righteous, no, not one: 11 There is none that understands, there is none that seeks after God. 12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
Every member of the human family, without exception, has had their share of deficiencies which Christ has had to make up with His own Divine merit. With Noah, it was the use of alcohol, with Abraham and Sarah it was lying, with David and Solomon it was porn and adultery, with Isaiah it was unclean lips, with all that it entails.
With James and John, it was a violent temper, and the list goes on and on. Not a single person has ever been born without deficiencies of some sort. Hence the reason why God sent not His Son into the world to condemn us, but that we might be saved through His life and death. The servant of The Lord, in addressing our inevitable failures puts it this way.
[The Desire of Ages. Pp 295] All the disciples had serious faults when Jesus called them to His service. Even John, who came into closest association with the meek and lowly One, was not himself naturally meek and yielding. He and his brother were called “the sons of thunder.” While they were with Jesus, any slight shown to Him aroused their indignation and combativeness. Evil temper, revenge, the spirit of criticism, were all in the beloved disciple.
2nd Corinthians 3:18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.
May The Lord add His blessing to the study of His word. God bless!
