Consider the following:
The commandments of the Old Covenant were to love God perfectly and absolutely. That's why the command consisted of loving Him with your whole self (mind, body, strength, and spirit). This is an impossible task! We were to also love others as ourselves (this fails too, because our love is always tainted in some way with selfishness). This also fails, because it falls short of God's perfect selflessness.
Matthew 22:34-40 - But when the Pharisees heard that Jesus had silenced the Sadducees, they gathered themselves together. One of them, a lawyer, asked Him a question, testing Him, "Teacher, which is the great commandment in the Law?" And He said to him, "'You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.' This is the great and foremost commandment. The second is like it, 'You shall love your neighbor as yourself.' On these two commandments depend the whole Law and the Prophets."
Here, Jesus was quoting from the Old Covenant:
Deuteronomy 6:4-5 - Hear, O Israel! The Lord is our God, the Lord is one! You shall love the Lord your God with all your heart and with all your soul and with all your might.
and
Leviticus 19:18 - You shall not take vengeance, nor bear any grudge against the sons of your people, but you shall love your neighbor as yourself; I am the Lord.
Under the New Covenant things are much different. We are commanded to believe in Jesus and to love as God has loved us.
John 6:28-29 - Therefore they said to Him, "What shall we do, so that we may work the works of God?" Jesus answered and said to them, "This is the work of God, that you believe in Him whom He has sent."
John 10:37-38 - If I do not do the works of My Father, do not believe Me; but if I do them, though you do not believe Me, believe the works, so that you may know and understand that the Father is in Me, and I in the Father.
Romans 4:4-5 - Now to the one who works, his wage is not credited as a favor, but as what is due. But to the one who does not work, but believes in Him who justifies the ungodly, his faith is credited as righteousness.
Hebrews 4:2-3 - For indeed we have had good news preached to us, just as they also; but the word they heard did not profit them, because it was not united by faith in those who heard. For we who have believed enter that rest.
1 John 3:21-23 - Beloved, if our heart does not condemn us, we have confidence before God; and whatever we ask we receive from Him, because we keep His commandments and do the things that are pleasing in His sight. This is His commandment, that we believe in the name of His Son Jesus Christ, and love one another, just as He commanded us.
1 John 4:16-21 - We have come to know and have believed the love which God has for us. God is love, and the one who abides in love abides in God, and God abides in him. By this, love is perfected with us, so that we may have confidence in the day of judgment; because as He is, so also are we in this world. There is no fear in love; but perfect love casts out fear, because fear involves punishment, and the one who fears is not perfected in love. We love, because He first loved us. If someone says, "I love God," and hates his brother, he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen. And this commandment we have from Him, that the one who loves God should love his brother also.
John 15:11-12 - These things I have spoken to you so that My joy may be in you, and that your joy may be made full. This is My commandment, that you love one another, just as I have loved you.
Ephesians 5:1-3 - Therefore be imitators of God, as beloved children; and walk in love, just as Christ also loved you and gave Himself up for us.
Ephesians 5:25 - Husbands, love your wives, just as Christ also loved the church and gave Himself up for her.
John 15:9 - Just as the Father has loved Me, I have also loved you.
Lastly, the standard under the New Covenant is not for us to ask God to forgive us in the same way we forgive others, as was the case under the Old Covenant (meaning, God's forgiveness of us is dependent on us first forgiving others), but rather that we recognize that God has already forgiven us, therefore we forgive:
Ephesians 4:32 - Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you.
Colossians 3:13 - Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you.
