Works may boast and say to us, I can get you to heaven, if you try hard and labor to do your best. Salvation is the gift of God to be received. We don't work to earn a gift, we simply receive it. "For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast" (Ephesians 2:8-9). It's not by your works, but by resting in the finished work of Christ alone. Rest in Christ through faith alone.
Rest in Christ by God's grace alone. It's about what God has done for us in Christ. It's what God is doing in us and through us. That's called grace, and its fulness is found in Jesus Christ our Lord (John 1:16).
Jesus says to you,"Come unto Me, all you who labor and are heavy laden, and I will give you rest"(Matthew 11:28). Jesus invites all who are weary to come to Him and find rest. The word rest refers to our relationship with God in Christ. Faith in Christ means we are completely depending upon Him to do in us what we cannot do for ourselves.
Rest in Christ through faith alone. That means your confidence, trust, and reliance is in Christ alone, to do in your life what you are unable to do by yourself. Only Jesus Christ can save you. That means you rest in Christ. Rest in God's love, mercy, and grace, believing on the Lord Jesus Christ (Acts 16:30-31).
