He that covereth a transgression seeketh love; but he that repeateth a matter separateth very friends. -Proverbs 17:9 KJV
Read the Second Letter to the Corinthians (2 Corinthians).
We are called to a ministry of reconciliation. We are to help reconcile our fallen world to a holy God.
How do we do this?
It is not by constantly telling people what they are doing is wrong. We should, ought to point out their sinfulness and need for a savior, but repeating it over and over and putting forth a air of judgmentalism, driving people away.
Instead, we acknowledge the sin, yes, but we make it clear that we still want to be with them and see them.
That we still love them, because God first loved us. (1 John 4:19)
We must cover their sins with the love of God, as He did for us with the blood of Christ. Then they will be able to see God’s grace that much more clearly.
Even with your brother or sister, your crazy mom or deadbeat dad, the customer who complains about everything or the cashier who messes up your order, and the driver who cut you off in traffic.
