2 Corinthians 5:17 ESV Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.
If you look at this Scripture from God's perspective you will see you are a new creation in Christ Jesus, the old things have passed away so that new things can come forth. God does not want us to continue to be set in our old ways, He does not want us leaning on our emotions and fleshly desires but wants us to change and depend upon the Holy Spirit of God. The Holy Spirit of God is the One who helps us to change and not to stay in our old sinful natures but encourages us to change and take on board the new nature of Christ Jesus. We must be of a willing heart and soul to be willing to change for Him. You can see in (2 Timothy 1:7 ESV) For God gave us a spirit not of fear but of power and love and self-control. This means we can think about all things in a proper way in Jesus Christ.
Whereas if we let our old nature take control of our thinking and not allow God’s Spirit the control He wants within our lives then we find that things do not go in the way we would like. We begin to get restless, discontented and irritable. This is one of the ways God uses us to show us we have stepped out of line and out of God’s will.The Holy Spirit of God convicts us of our sins and it is up to the individual person whether they want to repent from sin or not. He does not make us do anything we do not want to do. He gives us the choice to choose whether we want to repent from our sin and be made clean through Jesus Christ Name and Blood or we can hold onto our sin and stay where we are in sin until we make the choice to repent from our sin and ask Jesus to forgive us and He then sets us free from it. He gives us the free will to choose what we will want to do. From experience I have learnt it is always best to do things in the way God has written down for us to follow the principles of the Bible. The Bible is the example God has left for us to follow we must meditate upon the truth of God’s Word. We do not need to depend upon our emotions and feelings but need to depend upon the Holy Spirit of God having teachable spirits this will keep us in the centre of God’s will through Jesus Christ our precious Lord. He fills us with His love, grace, mercy and peace which keep us happy and contented giving us courage joy and happiness to live our lives for Jesus Christ.
