The appearance of Christ to Paul on the road to Damascus left him forever astounded at the goodness of God.
And I thank Christ Jesus our Lord, who hath enabled me, for that he counted me faithful, putting me into the ministry; Who was before a blasphemer, and a persecutor, and injurious: but I obtained mercy, because I did it ignorantly in unbelief. And the grace of our Lord was exceeding abundant with faith and love which is in Christ Jesus. This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief. Howbeit for this cause I obtained mercy, that in me first Jesus Christ might shew forth all longsuffering, for a pattern to them which should hereafter believe on him to life everlasting. Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen. (1 Timothy 1:12-17)
Seeing God precedes becoming like Him.
As for me, I will behold thy face in righteousness: I shall be satisfied, when I awake, with thy likeness. (Psalm 17:15)
Only to the degree we have seen and become like God can we do good like God.
Beloved, follow not that which is evil, but that which is good. He that doeth good is of God: but he that doeth evil hath not seen God. (3 John 1:11)
God designed that our seeing and tasting of His goodness would go beyond an experience of material blessings.
For when we were yet without strength, in due time Christ died for the ungodly. For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die. But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us. Much more then, being now justified by his blood, we shall be saved from wrath through him. For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life. (Romans 5:6-10)
Our calling to be like God is in fulfilled in our kindness toward those who continue to fall short of the way we would have them to be.
Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. For if ye love them which love you, what reward have ye? do not even the publicans the same? And if ye salute your brethren only, what do ye more than others? do not even the publicans so? Be ye therefore perfect, even as your Father which is in heaven is perfect. (Matthew 5:43-48)
For if ye love them which love you, what thank have ye? for sinners also love those that love them. And if ye do good to them which do good to you, what thank have ye? for sinners also do even the same. And if ye lend to them of whom ye hope to receive, what thank have ye? for sinners also lend to sinners, to receive as much again. But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind unto the unthankful and to the evil. Be ye therefore merciful, as your Father also is merciful. (Luke 6:32-36)
With the way God treated us before we got saved in mind, we are admonished to keep a right/godly attitude toward others before they turn around.
Put them in mind to be subject to principalities and powers, to obey magistrates, to be ready to every good work, To speak evil of no man, to be no brawlers, but gentle, shewing all meekness unto all men. For we ourselves also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another. But after that the kindness and love of God our Saviour toward man appeared, Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost (Titus 2:1-5)
God has designed that we become like Him as we continually keep in mind the mercy we have received and behold the glory of His goodness in Christ.
But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord. Therefore seeing we have this ministry, as we have received mercy, we faint not (2 Corinthians 3:18-4:1)
Only with a commitment to holiness and peace with all men will we end up seeing the Lord in ever increasing glory. Otherwise, the failures of others to meet our expectations and standards will allow bitter roots to spring up which will trouble us and defile others.
Follow peace with all men, and holiness, without which no man shall see the Lord: Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled (Hebrews 12:14,15)
