John 12:23-26, And Jesus answered them, saying, The hour is come, that the Son of man should be glorified. Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit. He that loveth his life shall lose it; and he that hateth his life in this world shall keep it unto life eternal. If any man serve me, let him follow me; and where I am, there shall also my servant be: if any man serve me, him will my Father honour.
We all die for some nor other thing as some die to have gadgets some for particular food and other for some of there passion or needs, we all are craving for things in this Earth (physical life) but dieing to live is to live with Lord (God) referring from John 12:23-26 in our heart we need to die to serve Lord, Die is to gain we know physical death leads to eternal life with Lord (only under belief and trust).
V24 expects the way Lord is planted to bring harvest for next. Here In this verse Jesus is speaking about his death to our sin and provide like for us (One who believe and trust). Jesus died for our sin so all who believe shall have eternal life and he died according to scripture, Acts 2:41 Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls.) Acts records the believers entering in numbers and Christ wants us to be in that number, it also applies to believers referring Matthew 16:25-26 For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it. For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul? We have to love Lord than our self.
V25 as believers we won’t protect protect our physical life but will protect Gods principle his teachings and not being self contended (selfish) but to have a desire on God and his words and to be fruitful for his Glory. As we are seeds that weather and die from this worlds desire and bring forth harvest for Lords Glory, Paul says to Timothy 2Timothy 1:7, For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind not to fear but teach with sound mind.
This is a message for believers but for unbelievers it is time to understand the free gift (eternal life) which is given from Lord.
