Hi Sam,
This is a good question and there is much in scripture to encourage you.
Let me recommend you read the whole of 1 Peter, and 2 Peter 1. He covers much of what matters in a very short space.
(NKJV)1 Peter 1
13 Therefore gird up the loins of your mind, be sober, and rest your hope fully upon the grace that is to be brought to you at the revelation of Jesus Christ; 14 as obedient children, not conforming yourselves to the former lusts, as in your ignorance; 15 but as He who called you is holy, you also be holy in all your conduct, 16 because it is written, "Be holy, for I am holy."
17 And if you call on the Father, who without partiality judges according to each one's work, conduct yourselves throughout the time of your stay here in fear; 18 [u]knowing[/u] that you were not redeemed with corruptible things, like silver or gold, from your aimless conduct received by tradition from your fathers, 19 but with the precious blood of Christ, as of a lamb without blemish and without spot.
20 He indeed was foreordained before the foundation of the world, but was manifest in these last times for you 21 who through Him believe in God, who raised Him from the dead and gave Him glory, so that your faith and hope are in God. 22 Since you have purified your souls in obeying the truth through the Spirit in sincere love of the brethren, love one another fervently with a pure heart, 23 [u]having been born again, not of corruptible seed [b]but incorruptible[/b], through the word of God which lives and abides forever[/u],
2 Peter 1
2 Grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord, 3 as His divine power has [b]given[/b] to us all things that pertain to [b]life[/b] and godliness, through the knowledge of Him who called us by glory and virtue, 4 [b]by which have been [u]given to us exceedingly great and precious promises[/u], that through these you may be [u]partakers of the divine nature[/u], having escaped the corruption in the world through lust[/b]. 5 But also for this very reason, giving all diligence, add to your faith ....
10 [u]Therefore, brethren, be even more diligent to make your call and election sure[/u], for [b]if [u]you[/u] do these things you will [u]never[/u] stumble; [/b]11 [b]for [u]so[/u] an entrance [u]will be supplied to you abundantly[/u] into the everlasting kingdom of our Lord and Savior Jesus Christ[/b].
12 For this reason I will not be negligent to remind you always of these things, though you know and are established in the present truth.
'supplied' = ministered or served
Galatians 4:19
My little children, for whom I labor in birth again until Christ is formed in you,
Earlier in the chapter Paul says this:
1 Now I say the heir, as long as he is a child, does not differ at all from a slave, though he is master of all, 2 but is under guardians and stewards until the time appointed by the father.
3 Even so we, when we were children, were in bondage under the elements of the world. 4 But when the fullness of the time had come, God sent forth His Son, born of a woman, born under the law, 5 to redeem those who were under the law, that we might receive the adoption as sons.
6 And because you are sons, God has sent forth the Spirit of His Son into your hearts, crying out, "Abba, Father!" 7 Therefore you are no longer a slave but a son, and if a son, then an heir of God through Christ.
[THIS BIT IS A WARNING]
8 But then, indeed, when you did not know God, you served those which by nature are not gods. 9 But now after you have known God, or rather are known by God, how is it that you turn again to the weak and beggarly elements, to which you desire again to be in bondage? 10 You observe days and months and seasons and years.
11 I am afraid for you, lest I have labored for you in vain.
