Like the title, does God love forever, unconditionally? I can't think of a being who is supposed to be more loving than God, so this is kind of a big question for me.
No, God does not love unconditionally. In fact, God hates the wicked.
However, those who have faith in Christ and accept him as their savior are loved unconditionally for eternity.
God’s love for us, is a purest form of all love and though it is seems to be conditional, whereby we have to be right with Him, it is at the same time forever unchanging in His nature, even when we are not right with Him in this world. So the door is always open for us to come back and be right with God, when we tread our journey here.
To know this deeper: our love towards God is basically conditional meaning we love God for our well being, for our needs, for our security etc. We love Him because we depend on Him and so it is not unconditional. When we have a cosy life we tend to side track God sensing the needlessness for Him. But God’s love for us, is not of this form. We our self experience and give such a pure form of love: the love that we have towards our children. This is the closest replica of God’s love for us. This love that we shower on our children is a pure form of love expecting nothing in return except the righteousness from our children. In fact this is not a condition as such, but a requirement for our own good.
The love that we bestow on our pets is similar to this. We get only satisfaction and happiness to be with them and expect nothing in return expect their wellbeing so that they remain with us.
So God loves us because we are His children, just like parents love their children. Though parents may at times falter in this but not God, for He said:
The Bible presents God as One who does not merely choose to love, but One who is love (1 John 4:16). It is a defining attribute of His.
It follows, then, that God always loves. He loved those about whom the Scriptures say, "every inclination of their hearts was only evil all the time." That's why it grieved God--because He loved them. If He hadn't loved those people, then we are left to wonder how they could grieve Him.
At the same time, God hates wickedness, and it's appropriate for God to hate that which hurts those He loves.
Now, this is not to say that God's love makes God unjust. He is simultaneously both just and loving. His justice demands that all sin be punished, while His love compelled Him to offer Himself as a substitute to pay the penalty of those sins. For those who accept His offer, God credits the meritorious payment of Christ to their accounts. For those who reject this, He is left to administer justice on those He loves.
