Phil 1:6, Num 23:19, 1 Thes 2:12, Rom 8:37-39, 1 Cor 1:9, 1 Pt 5:10, Jn 6:39-40, Jn 10:28-29, Jude 1:24-25

God is faithful. (Num 23:19, 1 Cor 1:9)

Num 23:19 God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?

1 Cor 1:9 God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord.

The God who called us will surely save us. (1 Thess 5:24, Phil 1:6, Jude 1:24-25)

1 Thess 5:24 Faithful is he that calleth you, who also will do it.

Phil 1:6 Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:

Jude 1:24 Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy, 25 To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen.

Even now, God strengthens us and gives us victory. (1 Pt 5:10, Rom 8:37-39)

1 Pt 5:10 But the God of all grace, who hath called us unto his eternal glory by Christ Jesus, after that ye have suffered a while, make you perfect, stablish, strengthen, settle you.

Rom 8:37 Nay, in all these things we are more than conquerors through him that loved us. 38 For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, 39 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.

God will allow all those who have entrusted us to hear the gospel of salvation. (Jn 6:39-40, Jn 10:28-29)

Jn 6:39 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. 40 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.

Jn 10:28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. 29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
