So this is for that person that is already on the edge of giving up. For you that has been thinking of how cruel life is and has been to you, for you that has not been able to imagine good or think goodness about yourself just because your life is not fast taking shape. This is to encourage you to wait on God and never give up on trusting.
Another side to this scripture is that many of us take for granted all that is written therein God's word. We probably are thinking he has forgotten he said he'd come but no he's giving us all a chance, a chance to amend, to renew, to be restored and all. Don't lose it, and please never lose it. Take not His love for granted.
You are loved dearly. God loves you deeply..
2Peter 3:9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance
