In the atonement, we see the character of God and what we learn is the foundation of our eternal privileges, “He who did not spare his own Son but gave him up for us all, how will he not also with him graciously give us all things?”. whatever else we receive from God, it cannot be compared with Jesus and since God did not spare His son then how could we doubt receiving what we need. The logic is simple, that if God has given us the greatest gift of all in giving us Christ, then what reason would there be for not giving lesser gifts. Yet even these lesser gifts are of great worth but they are lesser in comparison with Christ.
When Jesus taught His disciples how to pray, He told them a parable (Luke 11) and the conclusion to the parable causes us to reflect on the character of God compared to man, “If you then, who are evil, know how to give good gifts to your children, how much more will the heavenly Father give the Holy Spirit to those who ask him!”. There exists in some a fallen logic when it comes to the character of God. Some would have us believe that the Father God should not be trusted because their earthy father was absent. Those who understand the fatherhood of God by looking at the absent fatherhood of man is sadly led astray. Firstly by a poor imitation of fatherhood and secondly by concluding that God must be like human fathers. The comparison in the parable is that God is not like us and therefore no such comparison can be made.
A Just Judgement doesn’t require the Cross of Christ.
Why did God give His only son? When God gave His Son, He is not demonstrating one way that He is able to save and forgive sinners, He was accomplishing salvation in the only way it could be accomplished. What do you do when something can only be accomplished in one way? What is it that makes God giving His Son so necessary? It is not because we are bound in sin, it is not because we are sinful with only eternal damnation to look forward to. The judgement of God is necessary given the condition of humanity and we know that God could justly judge us in our sinful condition without saving us, but this is not what God does.
With God setting His love upon us, He was at the same time giving His only Son to the Cross. With God setting His love upon us, He remains the just judge and so must deal with our sin and He does, at the same time of accomplishing our salvation in Christ Jesus. Therefore His love for us does not mute, by-pass, ignore or render irrelevant the need to judge sin, but rather His love is expressed to us by Christ taking the judgement for our sin in our place on the cross. God who did not spare His own Son, will not spare anything else in loving us in all the ways He does.
