FORGIVING? IT'S UP TO YOU!
The Lord says: "forgive". Verse 12 conveys an understanding which is vital for carefree Kingdom living. Jesus emphasises the importance of forgiving by clarifying it:
"forgive us our debts (sins, trespasses)
forgive our debtors" (those who sin, trespasses, against us).
But, at the end of verse 13, immediately following the "Amen" ("so be it"), He says:
"... if you forgive men their trespasses, your heavenly Father will also forgive you.
But if you do not forgive men their trespasses, neither will your Father forgive your trespasses" (verses 14-15).
To ignore His words is to put an impenetrable barrier (to say the least) between the unforgiving Believer and God.
Obeying them renews a Believer's sonship with the Father.
Alongside forgiving the Lord calls a Believer to examine themselves. At the Lord's Supper Saints are told to do just that:
"... let a man examine himself, and so let him eat of the bread and drink of the cup.
For he who eats and drinks unworthily eats and drinks judgment to himself, not discerning the Lord’s body.
For this reason many are weak and sick among you, and many sleep.
For if we would judge ourselves, we would not be judged.
But when we are judged, we are chastened by the Lord, that we may not be condemned with the world," 1 Corinthians 11'28-32.
God has given His Children the privilege and the blessing of judging ourselves.
Being commanded to forgive someone can be a challenge because doing it can seem very unreasonable thing due to the harm that the person has inflicted.
When Jesus put the condition "as we" in place He knew about the challenge. Nevertheless, He also knew about the serious personal, spiritual consequences of unforgiveness.
So, why would any Believer, having been totally forgiven and unconditionally loved by God, put refusal in the way by not forgiving someone?
Turning away by refusing means that God can't hear us because our "manner" has become a blockage?
Be ... forgiving ... just as God in Christ forgave you.
