John 10:7-11 (NKJV)
Jesus the Good Shepherd
7
Then Jesus said to them again, “Most assuredly, I say to you, I am the door of the sheep. 8 All who ever came before Me[a] are thieves and robbers, but the sheep did not hear them. 9 I am the door. If anyone enters by Me, he will be saved, and will go in and out and find pasture. 10 The thief does not come except to steal, and to kill, and to destroy. I have come that they may have life, and that they may have it more abundantly.

11 “I am the good shepherd. The good shepherd gives His life for the sheep.

1 Corinthians 15:1-11 (NKJV)
The Risen Christ, Faith’s Reality
1
Moreover, brethren, I declare to you the gospel which I preached to you, which also you received and in which you stand, 2 by which also you are saved, if you hold fast that word which I preached to you—unless you believed in vain.

3 For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, 4 and that He was buried, and that He rose again the third day according to the Scriptures, 5 and that He was seen by Cephas, then by the twelve. 6 After that He was seen by over five hundred brethren at once, of whom the greater part remain to the present, but some have fallen asleep. 7 After that He was seen by James, then by all the apostles. 8 Then last of all He was seen by me also, as by one born out of due time.

9 For I am the least of the apostles, who am not worthy to be called an apostle, because I persecuted the church of God. 10 But by the grace of God I am what I am, and His grace toward me was not in vain; but I labored more abundantly than they all, yet not I, but the grace of God which was with me. 11 Therefore, whether it was I or they, so we preach and so you believed.

2 Corinthians 1:12-14 (NKJV)
Paul’s Sincerity
12
For our boasting is this: the testimony of our conscience that we conducted ourselves in the world in simplicity and godly sincerity, not with fleshly wisdom but by the grace of God, and more abundantly toward you. 13 For we are not writing any other things to you than what you read or understand. Now I trust you will understand, even to the end 14 (as also you have understood us in part), that we are your boast as you also are ours, in the day of the Lord Jesus.

2 Corinthians 12:14-15 (NKJV)
Love for the Church
14
Now for the third time I am ready to come to you. And I will not be burdensome to you; for I do not seek yours, but you. For the children ought not to lay up for the parents, but the parents for the children. 15 And I will very gladly spend and be spent for your souls; though the more abundantly I love you, the less I am loved.

Hebrews 6:13-18 (NKJV)
God’s Infallible Purpose in Christ
13
For when God made a promise to Abraham, because He could swear by no one greater, He swore by Himself, 14 saying, “Surely blessing I will bless you, and multiplying I will multiply you.” 15 And so, after he had patiently endured, he obtained the promise. 16 For men indeed swear by the greater, and an oath for confirmation is for them an end of all dispute. 17 Thus God, determining to show more abundantly to the heirs of promise the immutability of His counsel, confirmed it by an oath, 18 that by two immutable things, in which it is impossible for God to lie, we might have strong consolation, who have fled for refuge to lay hold of the hope set before us.
