How does God's mercy 'heal our backsliding'?

The healing of our backsliding, as mentioned in Hosea 14:4, signifies God’s restoration of His people who have strayed. This healing is not due to anything we can do; rather, it is a result of His mercy and the redemptive work of Christ. When we recognize our tendency to stray away from God, His promise to heal affirms that we can come to Him broken and needy. He willingly restores us, demonstrating that His love is a constant force in our lives and that His grace is sufficient to mend the wounds of our waywardness.
