Now to Him who is able to keep you from stumbling or falling into sin, and to present you unblemished [blameless and faultless] in the presence of His glory with triumphant joy and unspeakable delight,

The person who has My commandments and keeps them is the one who [really] loves Me; and whoever [really] loves Me will be loved by My Father, and I will love him and reveal Myself to him [I will make Myself real to him].”

I have loved you just as the Father has loved Me; remain in My love [and do not doubt My love for you].

When he arrived and saw the grace of God [that was bestowed on them], he rejoiced and began to encourage them all with an unwavering heart to stay true and devoted to the Lord.

We have come to know [by personal observation and experience], and have believed [with deep, consistent faith] the love which God has for us. God is love, and the one who abides in love abides in God, and God abides continually in him.

We know [with confidence] that anyone born of God does not habitually sin; but He (Jesus) who was born of God [carefully] keeps and protects him, and the evil one does not touch him.

And they overcame and conquered him because of the blood of the Lamb and because of the word of their testimony, for they did not love their life and renounce their faith even when faced with death.

The mercy

For the Law was given through Moses, but grace [the unearned, undeserved favor of God] and truth came through Jesus Christ.

to Timothy, my true son in the faith: Grace, mercy, and peace [inner calm and spiritual well-being] from God the Father and Christ Jesus our Lord.

to Timothy, my beloved son: Grace, mercy, and peace [inner calm and spiritual well-being] from God the Father and Christ Jesus our Lord.

Unto

so that, as sin reigned in death, so also grace would reign through righteousness which brings eternal life through Jesus Christ our Lord.

For the wages of sin is death, but the free gift of God [that is, His remarkable, overwhelming gift of grace to believers] is eternal life in Christ Jesus our Lord.

The one who believes in the Son of God [who adheres to, trusts in, and relies confidently on Him as Savior] has the testimony within himself [because he can speak authoritatively about Christ from his own personal experience]. The one who does not believe God [in this way] has made Him [out to be] a liar, because he has not believed in the evidence that God has given regarding His Son.
