Christ alone is sufficient for our salvation. Nothing needs to be added to His perfect work in order to be saved. He was made in every way like us in order to be a perfect propitiation. This new covenant is able to change our heart instead of religious laws and rules that only change us externally. If you go back to looking to laws and rules for salvation, you make no need for Christ to die for us. It is willful sin to turn away to something else as our salvation. This is looking to our works to save us, and no works of the flesh shall be justified. There will always be this temptation to look to something in addition to Christ for salvation. It will come as a way to find security in an external ordinance instead of trusting Christ by faith. External acts do not account for anything in salvation--they are however, necessary expressions of our saving relationship with God. If you think you need something else for salvation, you are saything that Christ is not enough, and you are trampling the Son of God underfoot, insulting the Spirit of grace. It is faith alone that will transform the believer from the inside out. For encouragement during trials, remember and reflect on the goodness and faithfulness of God in the past. Show others sympathy as they go through trials too. Have compassion, and suffer with them. In trespasses, don’t run away from God. Come boldly to the throne of grace in repentance. Don’t throw away your confidence in Christ. Allow the grace of God to work in and through you--don’t resist this grace. Grace comes from God, but the use of it is up to you. Persevere by faith, and don’t draw back! Exhort one another and hold fast your confidence until the end!
