Yes, there are many promises from the Lord God to us. But, there is one of them that is THE PROMISE. This is what the Holy Scriptures say:
"And this is the promise that he hath promised us, even eternal life." (1 John 2:25)
Let's meditate...
After all, the Lord Jesus said:
"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?" (Matthew 16:26)
But how can we have Eternal Life? The Word of God says:
"And this is the record, that God hath given to us eternal life, and this life is in his Son. He that hath the Son hath life; and he that hath not the Son of God hath not life. These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God." (1 John 5:11-13)
Whoever believes and wishes to receive the Lord Jesus into their heart, then pray like this:
Lord my God and my FATHER,
I repent of all the sins I have committed in life;
I do believe that Jesus is the Son of God, and that he died on the cross for my sins;
I also believe in my heart that Jesus was raised by You from the dead;
I confess and receive the Lord Jesus, as the only and sufficient Savior of my life;
I ask You, my God and my FATHER, to forgive me of all the sins I have ever committed, write my name in the Book of Life, and accept me into the Kingdom of Heaven;
I pray in the Name of my Lord and Savior Jesus and I thank You, with all my heart, eternally;
Amen.
So, let us remain in the Son Jesus and in the FATHER. Whoever does not have the Son does not have the FATHER either. But we, who believe in the Lord Jesus and the FATHER, must be faithful to the end, having the Son and the FATHER!
