Deut. 3:3 and Luke 6:35
Sometimes in our minds we can get all tangled up when in the old testament we read of Moses, at the Lord's command, slaughtering an entire people right down to the last survivor and then we read in the new testament Jesus commanding us to love our enemies? Are we not seeing two different God's here or at the very least God having changed his mind on how to act somewhere in between the last book in the old testament Malachi and the first book in the new, Matthew.
This is something that I have personally been thinking and persuing a clear answer for for sometime and I feel that recently for me the last few pieces of the puzzle have clicked into place and I would love share this with you.
The key to this conundrum I think lies in Romans 2:3 where Paul explains the Lord's kindness, forbearance and patience towards sin. What we often interpret as the Lord not acting in history, not displaying his wrath against judgement or the slow fulfilment of prophesy Paul actually explains as patience. One thing that is interesting to remember is that the time period covered by the old testament period is significantly longer than that of the new. Often we can mistakingly think that the Lord was constantly destroying one nations after another in judgement. But in actually fact there are long periods of patience recorded in the old testament where the Lord delays the punishment of a nation until their sin had reached a critical mass and then he steps in. The most obvious occasion is during the Lord's covenant making to Abraham in Genesis 15 where the Lord details to Abraham that the iniquity of the Amorites is not yet complete.
Another aspects of this problem is again detailed by Paul in Romans 12:19 where he records the Lord's command that vengeance is his and his only. If we take a careful look at the old testament we will discover that at each point that a nation is judged and wiped out it was always at the specific instruction from the Lord and whenever the Israelites decided to take things into their own hands and deal out a bit of their own judgement the Lord comdemed them for it.
The final piece of this puzzle comes together when we consider exactly how seriously the Lord considers sin. We must not take lightly the periods of patience depicting God as a God of Love only and forgetting his wrath and judgement towards sin. If we think that Gods wrath and judgement has been confined to the old testament period we need to remember Jesus' prophesy of the fall of Jesusalem and the historical recording of this we find in Josephus' writing. The death toll in Jerusalem itself without taking into account the surrounding towns was over a million. It is not easy reading and was a horrendous judgement that brought about an end to the age of the jews and signified the age of the gentiles.
And let us not forget the prophesy's of John of the end times when Jesus comes again in glory. There will again be an out pouring of wrath and woe to those whoes names are not written in the book of life as that day will be horrendous eclipsing all previous judgements. So let us not delay in seeking the face of the Lord and repenting of sin and leading other to do the same lest we become complacent that during this time of patience we forget the nearness of the final coming wrath!
