So we see that they could not enter in because of unbelief.
In Hebrews chapter 3, the author is revealing the supremacy of Jesus Christ, in that He provides for us perfect rest. There is no rest available to man that can compare to the rest we have in our Saviour. And who among us does not long for rest? Sure, we can go on vacation and relax, we can open a good book and kick our feet up, but this will result only in physical rest. What Jesus offers us is a deep, spiritual peace that passes all understanding.
Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.
I don’t know about you, but I want a peace and rest like that! But there is something hindering us from receiving this rest. It is unbelief. Just as the unbelief of the Hebrews wandering through the wilderness after being freed from Egypt kept them from entering the rest that God had for them in the land of Canaan(Heb. 3:11), so our hearts of unbelief will keep us from experiencing the rest Jesus has for us.
Are you experiencing depressing, anxiety, stress, or many other negative emotions? We all do at one time, but true belief, not just lip service, will free in from those things in Christ Jesus! We must believe that He is sufficient (2 Cor 12:9) to deal with any and all issues that we are dealing with. We just need to lay them at the foot of the cross, and Jesus promises to take those burdens from us. (Matt 11:28).
Believe, and rest in the peace of Christ!
