Mercy and truth are the pure nature of God and as we were created in the image of God, we are to imitate God our heavenly Father, as dear children, see Ephesians 5:1.
Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart: So shalt thou find favour and good understanding in the sight of God and man (Proverbs 3:3-4).
We are enjoying the mercies of God even though we don’t deserve it but yet He chose to have mercy on us and they are new every morning which is why we are not consumed, see Lamentation 3:22-23. Jesus said in Matthew 9:13, “But go ye and learn what that meaneth, I will have mercy, and not sacrifice: for I am not come to call the righteous, but sinners to repentance.” Also, see Hosea 6:6.
The word of God is divided into three parts; 1. Principles, 2. Promises, and 3. Prophecy. The principles are the ways of God, the rules of engagement of God’s kingdom which if we righteously practiced, we will enjoy a lot of benefits from the Lord. One of these is the favor of God. Proverbs 3:3 says, let not mercy and truth forsake you, that is, to be merciful to others (see Matthew 5:7) even to those that have wronged you just as we are enjoying the underserved mercy of God.
About the truth, we should love the truth, speak the truth, do the truth and stand for the truth. As 2 Corinthians 13:8 says, “For we can do nothing against the truth, but for the truth.” We should never attempt to do anything against the truth but always be for the truth. Only the truth has the potency to set people free (John 8:32). Now, Proverbs 3:4 says, we shall find favor and good understanding in the sight of God and man, that is after we have fulfilled verse 3.
The favor of God will qualify you for what you are not qualified for, just as the favor of God qualified Esther to be queen (see Esther 2:15). Favor of God will single you out for an uncommon miracle, as Mary was highly favored among women to be the mother of our Lord Jesus Christ (see Luke 1:27-28).
It should be our daily lifestyle as images of God in Christ Jesus to always do good and not be weary of doing good (And let us not be weary in well doing: for in due season we shall reap, if we faint not, Galatians 6:9). Proverbs 11:27 says, we should be diligent about doing good to procure or obtain the favor of God, also see Proverbs 12:2.
Don’t because someone has wronged you stop doing good, don’t allow the sin of others to remote you to fall into sin. Jesus never did, He was anointed with Holy Spirit and He went about doing good (see Acts 10:38), you also have the same Spirit as you are in Christ Jesus. Remember Philippians 4:13, “I can do all things through Christ which strengtheneth me.”
