We do not want you to become lazy but to imitate those who through faith and patience inherit what has been promised. Heb:6:12 Being lazy in faith is a dangerous thing - not actively working out the salvation you have freely received by grace. Not actively doing things because you are saved. Continuing on things which once entertained you. May be harmless things. But it quenches the Spirit in you. Not feeding on the right things, so then the new man is stunted; and feeding on the world's things so then the old man is still allowed to grow.. Forgetting the fact that the old man is dead. Proactively do things out of your faith. So that you will inherit what has been promised. Are you lazy in applying your faith in testing times? Are you lazy in spending time with the Word of God? Are you lazy in praying and fasting? Then it would be hard to inherit what has been promised.
We do not have a high priest who is unable to sympathize with our weaknesses. Heb:4:15 A high priest who sympathizes with us. A meaningful sympathy by someone who is able to help you in your weaknesses. Who knows what exactly you go through in your time of trouble. Because He has been tempted in every way as you have been, yet without sin. He has overcome every single one of them and out of His love and sympathy and empathy to you; He is willing to be with you and help you. Therefore we can approach the throne of grace with confidence. Every time you approach this throne of grace, filled with empathising love to you, you can be confident not to be shewed away, you can be confident not to blamed for your repeated failures and naivety. You can be confident of receiving mercy and grace which has been lavished upon you. Image courtesy: https://christianliferesources.com/family-topics/marriage/sympathy-feeling-with-others-not-for-them
