“For thus says the Lord God: Behold, I, I Myself will search for My sheep and will seek them out.” -Ezekiel 34:11
This He does at the first when His elect are like wandering sheep that know not the Shepherd or the fold. How wonderfully doth the Lord find out His chosen! Jesus is great as a seeking Shepherd as well as a saving Shepherd. Though many of those His Father gave Him have gone as near to hell-gate as they well can, yet the Lord by searching and seeking discovers them and draws nigh to them in grace. He has sought out us: let us have good hope for those who are laid upon our hearts in prayer, for He will find them out also.
The Lord repeats this process when any of His flock stray from the pastures of truth and holiness. They may fall into gross error, sad sin, and grievous hardness; but yet the Lord, who has become a surety for them to His Father, will not suffer one of them to go so far as to perish. He will by providence and grace pursue them into foreign lands, into abodes of poverty, into dens of obscurity, into depths of despair; He will not lose one of all that the Father has given Him. It is a point of honor with Jesus to seek and to save all the flock, without a single exception. What a promise to plead, if at this hour I am compelled to cry, “I have gone astray like a lost sheep!”
