Forgiveness from God is conditional or is it?

Matthew 6 14 For if ye forgive men their trespasses, your heavenly Father will also forgive you: 15 But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.  -kjv 14 For if you forgive other people when they sin against you, your heavenly Father will also forgive you. 15 But if you do not forgive others their sins, your Father will not forgive your sins.  -niv 14 “For if you forgive people their wrongdoing, your heavenly Father will forgive you as well. 15 But if you don’t forgive people, your Father will not forgive your wrongdoing. -hcsb Observations and comments: Here, the verse is appearing to say that forgiveness from God is conditional on our forgiveness of other's trespasses against us. This line of reasoning is in alignment of where our performance earns favour from God. Reasoning behind this: Our performance of forgiveness of others brings us God's forgiveness. If we don't perform forgiveness, God will not forgive us. But God is love. If He loves us, will he not also forgive us? Maybe this can be answered by the question, if we love God, then would we not forgive others also since God has also forgiven us? This brings me to the verse 1 John 4:8 which says that the one who does not love does not know God. If we do not know God, we are not God's children. So, if we do not forgive then we are not God's children. It means that if we belong to God, we are to forgive but not because we obey it as a rule but because we love God. Does it mean we are expected to forgive? It certainly does not seem helpful if we are expected to because the expectation can be a harsh driver without leading to true forgiveness from us.
