Matthew 5:7 (KJV) Blessed are the merciful: for they shall obtain mercy.
Do you need the blessing of mercy from GOD? Then be merciful.
Do you need to escape the judgment of GOD? Then be merciful. 
James 2:13 (KJV) For he shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment.
If we do not show mercy then we be judged without mercy.
But mercy triumphs over judgement. That is mercy is superior over judgement.
So we need to ask ourself how can we be merciful?
First we need to believe in the gospel (good news – see The gospel and judgement – 2024.05.17) of Jesus Christ. Through that we are reconciled to GOD. We turn from our ways to GOD’s ways (repentance) and He will empower us by the Holy Spirit to obey Him and therefore show mercy to those around us.
The parable that Jesus taught in Matthew 18 gives us a great example of showing and not showing mercy”
“Matthew 18:21-35 (KJV) Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times? 22 Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven. 23 Therefore is the kingdom of heaven likened unto a certain king, which would take account of his servants. 24 And when he had begun to reckon, one was brought unto him, which owed him ten thousand talents. 25 But forasmuch as he had not to pay, his lord commanded him to be sold, and his wife, and children, and all that he had, and payment to be made. 26 The servant therefore fell down, and worshipped him, saying, Lord, have patience with me, and I will pay thee all. 27 Then the lord of that servant was moved with compassion, and loosed him, and forgave him the debt. 28 But the same servant went out, and found one of his fellowservants, which owed him an hundred pence: and he laid hands on him, and took him by the throat, saying, Pay me that thou owest. 29 And his fellowservant fell down at his feet, and besought him, saying, Have patience with me, and I will pay thee all. 30 And he would not: but went and cast him into prison, till he should pay the debt. 31 So when his fellowservants saw what was done, they were very sorry, and came and told unto their lord all that was done. 32 Then his lord, after that he had called him, said unto him, O thou wicked servant, I forgave thee all that debt, because thou desiredst me: 33 Shouldest not thou also have had compassion on thy fellowservant, even as I had pity on thee? 34 And his lord was wroth, and delivered him to the tormentors, till he should pay all that was due unto him. 35 So likewise shall my heavenly Father do also unto you, if ye from your hearts forgive not every one his brother their trespasses.”
Let us therefore follow Jesus and walk in GOD’s ways, in the wisdom Jesus Christ has given us by being full of mercy instead of walking in earthly wisdom as described in the book of James
“James 3:13-18 (KJV) Who is a wise man and endued with knowledge among you? let him shew out of a good conversation his works with meekness of wisdom. 14 But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth. 15 This wisdom descendeth not from above, but is earthly, sensual, devilish. 16 For where envying and strife is, there is confusion and every evil work. 17 But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy. 18 And the fruit of righteousness is sown in peace of them that make peace.”
