The words of YHVH are never futile or in vain. They ALWAYS accomplish what He wishes for them to do. For the many who do not hear, there is always the one who will take His word to heart and begin a new life in Him.
As Yeshua spoke His parables, He knew there would be the few who would really understand what He was saying.
Sometimes we also feel like our efforts are not making a difference…it is YHVH who gives the increase. Those whom He wants to hear will hear. Those whom He wants to respond will respond.
The time is coming when men will seek after His word and not find it…
10 “For as the rain comes down, and the snow from the heavens, and do not return there, but water the earth, and make it bring forth and bud, and give seed to the sower and bread to the eater, 11 so is My Word that goes forth from My mouth – it does not return to Me empty, but shall do what I please, and shall certainly accomplish what I sent it for.
Always, seek the truth…rethink, relearn, return
