A person has to learn to trust what Jesus says to do.
And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.
And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
For
if Abraham were justified by works,
he hath whereof to glory;
but not before God.
For what saith the scripture?
Abraham believed God, and it was counted unto him for righteousness.
Now to him that worketh is the
reward not reckoned
of grace, but
of debt.
But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
Even as David also describeth the blessedness of the man, unto whom
God imputeth righteousness without works,
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous
But after that the kindness and love of God our Saviour toward man appeared,
Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
Which he shed on us abundantly through Jesus Christ our Saviour;
That being justified by his grace, we should be made heirs according to the hope of eternal life.
And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God
He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.
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.
I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
