We can have eternal life in one way, and what is that way? Converting ourselves to Christ and leaving everything that is not pleasing to God, following His commandments and fulfilling them above any obstacle.
Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
When we leave everything behind and cling to the faith that is in the Lord, all things will be made new because we left behind everything that prevented us from following the Lord. Everyone who comes to Christ passes from death to life.
Because that is what His holy word says, that He is the way, the truth and the life, but if we deny Him we will have nothing, because there is no other in which we can trust and be saved, He is our salvation and in Him we must trust every day.
Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.
As we believe we must also trust in the Lord, He is our helper and strength, it is good that we believe His word every day, just as this man named John advised us to seek God, that we believe only Him because if we believe in Him will have eternal life, and there will not come condemnation to us, and this is the reason why we should look for Him, because if we do this we will pass from death to life.
Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live.
Do not ignore these words, but we must believe in the promise of the Lord, because He promises and He fulfills, remember He is eternal life, do not faint because the day of the Lord in your life will come, where you will hear His voice and you will rise from between the deads.
